Seasonal changes of humoral and cellular immune responses to Japanese cedar (Cryptomeria japonica) pollen allergens in Japanese monkeys (Macaca fuscata) with pollinosis

The natural occurrence of Japanese cedar [Cryptomeria japonica (CJ)] pollinosis has been reported in Japanese monkeys (Macaca fuscata). The present study was designed to investigate seasonal changes in immunological reactions to CJ pollen allergens in monkeys with CJ pollinosis. Blood samples were collected from six monkeys with CJ pollinosis before and after CJ pollen season. Seasonal changes in specific IgE and IgG to major allergens (Cry j 1 and Cry j 2) were observed before and after CJ pollen season. The humoral responses decreased significantly before CJ pollen and increased after CJ pollen season. Similar seasonal changes in peripheral blood mononuclear cells proliferative responses to CJ allergens were observed before and after CJ pollen season. These humoral and cellular immune responses might serve as a biomarker for assessing new immunotherapies for monkeys with pollinosis.     

Clinical efficacy of apple polyphenol for treating cedar pollinosis

A double-blind comparative study was conducted on cedar pollinosis patients in order to evaluate the treatment efficacy of apple polyphenol (Ap). Ap was administered (500 mg) once daily for 12 weeks, starting about 2 weeks prior to cedar pollen dispersion. Pollinosis symptoms during the study were evaluated according to the classification in the guidelines for allergic rhinitis diagnosis and treatment. The results show that the sneezing score was significantly lower for the Ap group than with the placebo group during the early period of pollen dispersion and during the main dispersion period. In addition, no adverse reactions were induced by Ap during the study. These results suggest that Ap may alleviate the symptoms of cedar pollinosis.     

An approach for the conquest of the sugi pollinosis using plant growth regulation.

The sugi (Cryptomeria japonica) pollinosis becomes representative allergic disease in early spring in Japan. However, effective treatment for the sugi pollinosis and countermeasure against pollen of C. japonica at its source have not been developed in a practical sense. In this paper, the research aiming to prevent dispersion of pollen of the C. japonica is introduced on application and practical application to the field from the laboratory using the growth regulation of the plant. We found that formation of male flower bud in C. japonica could be suppressed by TNE, since the 3 beta-hydroxylase is inhibited by the action of Trinexysapacethyl, TNE.     

Epidemiologic studies on allergic diseases among rural and urban school children in Poland

451 rural children (group I) and 2000 urban children (group II) aged 10-16 years from Toruń province were inquired by a questionnaire to their parents or guardians. 9.09% of children in the country and 13.45% of those living in the city of Toruń suffered from hypersensitivity disorders; bronchial asthma was reported in 2.22% and 3.05% of cases, allergic rhinitis--in 3.77% and 7.15%, allergic conjunctivitis--in 1.33% and 2.75%, allergic edema--in 0.44% and 0.60%, urticaria--in 1.55% and 3.50%, and infantile eczema--in 0.44% and 2.10% of cases, respectively. The pollinosis prevalence rate was 2.00% in group I and 1.85% in group II. At least 2 various forms of hypersensitivity coexisted in 30.48% of allergic urban children (64.86% of patients with pollinosis among them); infantile eczema preceded allergic rhinitis and bronchial asthma symptoms in 6.29% and 11.47% of cases, respectively, while allergic rhinitis occurred before the onset of bronchial asthma in 24.59% of asthmatic children. 37.10% of individuals with positive family history of allergic conditions also fell ill with some diseases of this nature, while in those with negative family history allergy occurred only in 10.22% of cases. From environmental factors mother's diseases during pregnancy, bottle feeding and a regular diet during the first year of life, frequent respiratory infections in the early childhood and poor living conditions increased the risk of allergic diseases or aggravated their course in the population examined.     

Effects of polysaccharide derived from black currant on relieving clinical symptoms of Japanese cedar pollinosis: a randomized double-blind, placebo-controlled trial

We investigated the efficacy of the polysaccharide derived from black currant, named cassis polysaccharide (CAPS), for inhibiting Japanese cedar pollinosis symptoms and improving quality of life by a randomized double-blind, placebo-controlled trial in 2006. A total of 28 subjects were enrolled in the study, and 10 subjects in each group completed the trial. Although there was no significant difference between the CAPS and placebo group in the weekly mean value of any symptom in the daily symptom diary at any time, a smaller degree of final symptom aggravation was found in the CAPS group. Significant aggravation of the score was finally observed in the placebo group with inferior conch swelling and with sneezing, itchy nose, itchy eye and watery eye in the Japan rhino-conjunctivitis quality of life questionnaire assessment, while the changes observed in the CAPS group were not significant. In conclusion, our findings clearly indicate that CAPS would be useful as a food supplement in assisting the treatment of Japanese cedar pollinosis.     

The sexual psychopath in California

In California sexual offenders apprehended by the law are examined by court-appointed psychiatrists to determine whether they are "sexual psychopaths" as defined by California law and need treatment in a mental hospital. This paper outlines the criteria to be used as guides in properly selecting the persons for treatment. In general, sexual offenders fall into four categories. The first group consists of persons who cannot maintain proper control over their sexual impulses but whose acts do not constitute them a menace to the health and safety of others. They are not "sexual psychopaths" and their cases should be handled on their legal merits. The second group embraces persons who have committed a sexual offense on only one occasion and while under the influence of abnormal or unusual environmental stress. They are not considered "sexual psychopaths."The third is made up of persons completely out of step with the social culture. They often have long criminal histories or long histories of social maladjustment. They are impulsive in their behavior and not remorseful of their misdeeds. Sexually deviant acts committed by such individuals are often incidental to their general asocial and amoral behavior. They do not suffer from inability to control sexual impulses. Their offenses should be judged according to the legal merits of the case.True "sexual psychopaths" have deviant menaceful sexual impulses and are not able to control them. The vast majority of these persons are those who have committed sexual offenses against children. The California State Department of Mental Hygiene has a maximum security hospital which is charged with the care and treatment of "sexual psychopaths."     

Modeling experimental pollinosis

Experimental pollinosis was modelled on guinea pigs. The animals were placed in a cell in which an allergen-water-dialyzed extract of ambrosia pollen was dispersed by means of coaxial pulveriser. Homocytotropic antibodies serving as indices of animal sensitization to the specific allergen formed in guinea pigs as a result of aerosol sensitization. Sensitization of the animals to the ambrosia allergen was accompanied by an increase of sensitivity of the broncho-pulmonary apparatus and was characterized by the bronchospastic reaction in resolving inhalation or inrtavenous injection of a specific allergen.     

Purification and characterization of 31-kDa palm pollen glycoprotein (Ela g Bd 31 K), which is recognized by IgE from palm pollinosis patients

A basic glycoprotein, which was recognized by IgE from oil palm pollinosis patients, has been purified from oil palm pollen (Elaeis guineensis Jacq.), which is a strong allergen and causes severe pollinosis in Malaysia and Singapore. Soluble proteins were extracted from defatted palm pollen with both Tris-HCl buffer (pH 7.8) and Na-acetate buffer (pH 4.0). The allergenic glycoprotein was purified from the total extract to homogeneity with 0.4% yield by a combination of DEAE- and CM-cellulose, SP-HPLC, and gel filtration. The purified oil palm pollen glycoprotein with molecular mass of 31 kDa was recognized by the beta1-2 xylose specific antibody, suggesting this basic glycoprotein bears plant complex type N-glycan(s). The palm pollen basic glycoprotein, designated Ela g Bd 31 K, was recognized by IgE of palm pollinosis patients, suggesting Ela g Bd 31 K should be one of the palm pollen allergens. The preliminary structural analysis of N-glycans linked to glycoproteins of palm pollens showed that the antigenic N-glycans having alpha1-3 fucose and alpha1-2 xylose residues (GlcNAc(2 to approximately 0)Man3Xyl1Fuc(1 to approximately 0)GlcNAc2) actually occur on the palm pollen glycoproteins, in addition to the high-mannose type structures (Man(9 to approximately 5)GlcNAc2).     

Sensitivity to mugwort pollen allergens (Artemisia vulgaris)

The author has found that 42% of patients with pollinosis had positive skin reactions with mugwort (Artemisia vulgaris) pollen allergens. The majority of tested patients (139 out of 187) were also allergic to grass pollens. However, hypersensitivity to mugwort pollen allergens was isolated and did not accompany grass pollen allergy. The symptoms of pollinosis appeared in this group later than in patients sensitive to grass pollen allergens only (over 21 years of age in 71%). Bronchial asthma was diagnosed in 40% of these patients and allergic skin reactions in 25%. Sensitivity to mugwort pollen allergens was accompanied by the sensitivity to pollen allergens of Graminae family of plants in 80% of cases. The author suggests that sensitivity to mugwort pollen allergens is the second most frequent cause of the pollinosis and is diagnosed too rarely. Failures of desensitization in patients sensitive to pollen allergens of Graminae family of plants may often result from coexisting sensitivity to mugwort pollen allergens as this sensitivity produces not only season but perennial clinical symptoms in nearly 50% of patients. The author discusses also botanical relations and cross-reactions in allergy to mugwort and ragweed pollen allergens.     

Lactobacillus strains stabilize intestinal microbiota in Japanese cedar pollinosis patients

A randomized double-blind, placebo-controlled trial was conducted to ascertain the intestinal microbiota-altering properties of LGG and L. gasseri TMC0356 (TMC0356) in Japanese cedar Cryptomeria japonica pollinosis patients. Fecal bacteria communities were examined before and after fermented milk administration using culture, FISH and T-RFLP methods. Test group subjects showed the presence of LGG and TMC0356 along with a significant increase in fecal lactobacilli ( P < 0.001) after giving LGG and TMC0356 fermented milk. Culture and FISH analysis revealed no significant changes in other intestinal bacterial groups. Each subject exhibited a characteristic T-RFLP profile pattern that varied quantitatively and qualitatively with JCP shedding. Profile changes were observed in 53% of placebo group subjects and in 21% of test group subject's post-administration, indicating that LGG and TMC0356 suppressed intestinal microbiota changes in JCPsis patients. The results suggest that intestinal microbiota might be more sensitive to exposure to environmental allergens than expected from the results of general culture method studies. Stabilization of intestinal microbiota by selected probiotic strains such as LGG and TMC0356 could be beneficial to homeostasis of the intestinal microbiota and useful in the management of JCPsis.     

A correlation study between airborne pollen and cases of pollinosis in humans

This study aims to establish themathematical relationship between allergenicpollen in the air and clinical cases ofpollinosis (hay fever) in humans, and toevaluate the immediate effect of wind and rainon such cases. The pollen was collected inFigueres, Catalonia, Spain (42°30 Nand 3° E), through a filtration method,in the spring of 1998. Skin tests revealed thatthe antigenic taxa are Olea europaea,Plantago sp., Parietaria officinalisand Gramineae. A linear correlation –with the number of days with presence of pollenas the abscissa and the number of days withcoincidence of pollinosis as the ordinate – wasperformed. The linear correlation coefficientwas 0.9285, at the limit of a directcorrelation by two degrees of freedom.Furthermore, a negative relationship wasobserved between the number of days with rainand number of days with pollinosis, and apositive relationship between the number ofdays with fixed wind speed and number of dayswith pollinosis.     

Improving tetanus prevention in the Krasnodar area taking the current epidemic situation into account]

An increase of percentage of elderly persons among those who fell ill with tetanus (70%) was noted against a sharp reduction of tetanus incidence under the effect of mass active immunization against this disease. A study of immunity in older and elderly individuals showed the percentage of immune persons among them to be rather low (48.8--55.6%). Due to difficulty of elderly individuals embracement by vaccination the authors suggest a single immunization scheme with a double toxoid dose (20 BU) followed by revaccination with 10 BU in one year. A total of 21 472 persons were placed under observation. The suggested immunization scheme was harmless, promoted stimulation of antitetanus immunity in persons vaccinated earlier; as to unvaccinated persons--it created a favourable immunological preparedness for revaccination, permitting to do without any antitetanus serum in case of trauma.     

Ought We to Sentence People to Psychiatric Treatment?

In principle, there seem to be three main ways in which society can react when people commit crimes under influence of mental illness.
(1) The standard model. We excuse them. If they are dangerous they are detained in the interest of safety of the rest of the citizens.
(2) The Swedish model. We hold them responsible for their criminal offence, we convict them, but we do not sentence them to jail. Instead, we sentence them to psychiatric treatment.
(3) My model. We sentence them to jail, but offer them (voluntary) psychiatric treatment.
The advantages of my model are obvious. We get a clear delineation of roles. We allow the psychiatrist to be just a doctor, not a warden. We liberate psychiatry of the objective of deciding whether people who were mentally ill when they committed criminal offences 'could have acted otherwise'— a hopeless task. We allow that psychiatrists live up to their professional ethical code (the Hawaii Declaration). We treat psychically ill persons as 'normal', we allow them to repent their crimes, which renders easier their recovery.
However, two objections to my model come to mind. First of all, is it not unfair to sentence people to jail who could not help doing what they did? And, secondly, the question of fairness set to one side, is it not inhumane to sentence mentally ill persons to jail? Is it not inhumane to the mentally ill persons themselves, and does it not mean that they will be a burden to other prisoners?
In my paper I show that, if our system of criminal punishment takes a civilised form, neither of these objections carries any weight.     

Minor pollinosis fromCryptomeria japonica in Varese,northern Italy. Aerobiological monitoring and main clinical features

In the last 2 years, we have conducted an aerobiological monitoring program ofCryptomeria japonica, a plant belonging to the family of Taxodiaceae that sometimes causes pollinosis in the period from February to April. Throughout 1994, we checked the incidence of its sensitization and the clinical effects in 85 subjects with correlated seasonal symptoms, who gave a positive skin prick test (SPT) for Betulaceae and/or Corylaceae. Twenty-five patients (29.4%; 19 M; 6 F; mean age, 38.8 years) all with oculorhinitis, were SPT positive to an allergenic extract ofCryptomeria. RAST confirmed this positivity in 44% of the cases. No patients showed monosensitization forCryptomeria to either SPT or RAST. Two subjects gave a positive result on specific nasal provocation. RAST inhibition showed no cross-reaction betweenCryptomeria and birch pollen. During the pollen season each patient made a list, scoring symptoms and specifying any drugs used, so we could correlate these elements with aerobiological observations. The pollen concentration probably exceeded the allergizing threshold forCryptomeria on 8 days during 3 months of recording. The intensity and duration of symptoms seemed to be mainly influenced by sensitization to Betulaceae and Corylaceae. It is thus possible that a combination of ‘minor’ pollinosis may produce seasonal symptoms in allergic patients.     

The signaling function of an extra‐floral display: what selects for signal development?

The vertical inflorescences of the Mediterranean annual Salvia viridis carry many small, colorful flowers, and are frequently terminated by a conspicuous tuft of colorful leaves ('flag') that attracts insect visitors. Insects may use the flags as indicators of food rewards in the inflorescences below, as long-distance cues for locating and choosing flowering patches, or both. Clipping of all flags from patches of inflorescences in the field reduced the number of arriving insects, but not the total number of inflorescences and flowers visited by them. The number of flowers visited per inflorescence increased with inflorescence size, and inflorescence and flower visits rates significantly increased with patch size. Six percent of the plants in the study population did not develop any flag during blooming, yet suffered no reduction in seed set as compared to flag-bearing neighboring individuals. Removal of flags from all inflorescences in a patch reduced seed set in comparison with untreated controls, while flag clipping from ten randomly selected inflorescences in a patch did not decrease seed production. These results suggest that flags signal long-distance information to potential pollinators (possibly indicating patch location or size), while flower-related cues may indicate inflorescence quality.
Plants that do not develop flags probably benefit from the flag signals displayed by their neighbors, without bearing the costs of signal production. Greenhouse-grown S. viridis plants allocated a low proportion of their biomass to flags. Plants grown under water stress did not reduce biomass allocation to flags as compared to irrigated controls. Water loss rates of picked flags were lower than those of picked leaves. These findings suggest that the expenses of flag production and maintenance are modest, reducing the selective advantage of individuals that do not carry flags. We discuss additional potential evolutionary mechanisms that may select for flag production.     

IgG1 and IgG2 antibody responses to Plasmodium falciparum exoantigens correlate inversely and positively, respectively, to the number of malaria attacks

Abstract In Manarintsoa, near Antananarivo, Madagascar, two groups of patients were defined in terms of malaria clinical immune status: Group MA⁺ consisted of 36 patients who suffered from between one to four malaria attacks (MA) during the 20-week study, and Group MA⁻ who comprised of 48 persons who did not have any malaria attacks during this time. In group MA⁺, IgM and IgG antibody levels to Plasmodium falciparum exoantigens (E-Ag) were inversely related to the number of malaria attacks. The level of IgM antibodies were significantly higher in group MA⁺. In contrast, IgG, IgG1, IgG2, IgG3 and IgG4 antibodies to E-Ag were significantly higher in group MA⁻. The level of IgG1 antibodies was inversely correlated, and IgG2 antibodies were positively correlated to the number of malaria attacks.     

Genetic and Epidemiologic Evaluation of Dysplastic Nevi

Dysplastic Nevus Syndrome (DNS) has been defined as that trait characterized by the presence of at least one dysplastic melanocytic nevus. DNS was originally described in kindreds having multiple members with melanoma. Various types DNS have been described in other situations to include individuals with apparently sporadic cases, familial DNS without melanoma and individuals with apparently sporadic DNS with melanoma. These categories are based on historical information in general, and not on examination of family members. In all cases, the presence of dysplastic nevi appear to confer some increased risk of melanoma, which varies between the groups. Similarly cutaneous melanoma is thought to occur in several distinct populations-random individuals without DNS, individuals with sporadic DNS, and those with familial DNS. Genetic analysis of DNS has been largely confined to the classically ascertained kindreds associated with melanoma. These studies have usually used diagnostic criteria based on pathology of clinically selected material, and that evidence suggests that DNS is inherited as an autosomal dominant trait in these families. Surveys of the general population have detected rates of dysplastic nevi of 5% 20%. In our Utah-based studies, we have evaluated probands and family members from three groups. These included kindreds with multiple occurrences of melanoma, random individuals with at least one dysplastic nevus, and cases of melanoma with unknown family history. Controls were spouses of study subjects. We sought to determine the percentage of each group associated with dysplastic nevi and/or genetic DNS. The range of phenotype of patients with dysplastic nevi was large with some individuals having few nevi, none of which were clinically atypical, and others having greater than 100 nevi. The prevalence of dysplastic nevi in at least one of two biopsies in Utah population controls is presently Wtimated at 62%. Some probands with melanoma as well as some of their relatives had elevated numbers of nevi, suggesting that this predisposition to melanoma may be inherited.

Immunoenzyme test system with monoclonal antibodies to human IgG4 in the determination of allergen-specific antibodies in pollinosis

ELISA for determination of allergen-specific IgG4 antibodies was developed with the help of monoclonal anti-IgG4 antibodies obtained by classic hybridoma technique. Subclass specificity of antibodies were studied in sera of 108 patients suffering from pollinosis. Antibodies of this isotype were found in the majority of patients with tree pollen allergy but not in patients with grass pollen allergy. The level of IgG4 antibodies correlated with the severity of the disease but not with the intensity of skin tests. Specific hyposensitization resulted in significant increase of IgG4 antibody level in patients with tree pollen allergy. Determination of IgG4 antibodies is proved to be useful to reveal tree pollen allergy and to monitor hyposensitization therapy.
