湘华鲮外周血细胞形态特征及嗜中性粒细胞 吞噬与杀菌能力

采用血涂片、显微测量、血细胞计数及嗜中性粒细胞吞噬功能和氯化硝基四氮唑蓝还原试验方法,于光学显微镜下观察分析三种水体湘华鲮（Sinilabeo decorus tungting）外周血细胞形态结构、大小、种类及数量。结果表明,湘华鲮外周血细胞中有红细胞、血栓细胞、粒细胞、淋巴细胞和单核细胞,红细胞比例最高,达80%以上,白细胞中血栓细胞最多,占70% ~ 74%。大水面网箱养殖的湘华鲮外周血红细胞数量显著低于水泥池和土池养殖个体（0.01 < P < 0.05）,而白细胞的数量、种类及各类白细胞所占比例较为稳定,不随养殖方式的变化而发生显著变化（P > 0.05）,但水泥池湘华鲮嗜中性粒细胞的吞噬与杀菌能力较其他两种养殖方式显著下降（0.01 < P < 0.05）。因此,建议湘华鲮宜在水质良好的流水环境中养殖。     

濒危鱼类稀有白甲鱼外周血细胞特征

为了研究濒危鱼类稀有白甲鱼（Onychostoma rara）外周血细胞的特征,以采自长江中游沅江水系清水江共计21尾稀有白甲鱼的血液为材料,采用常规方法对稀有白甲鱼外周血细胞的组成、形态、大小和数量进行了观测。结果显示,稀有白甲鱼红细胞数量为（1.75±0.44）×106 个/ L,白细胞数量为（4.91±1.95）×105 个/ L。在血涂片上共计观察到了5种白细胞,包括淋巴细胞、血栓细胞、单核细胞、嗜中性粒细胞和嗜酸性粒细胞,没有发现嗜碱性粒细胞。其5种白细胞数量比例差异较大,其数量比例关系为：淋巴细胞>血栓细胞>嗜中性粒细胞>单核细胞>嗜酸性粒细胞。这5种白细胞的大小也有所不同,其大小关系为：单核细胞>嗜中性粒细胞>嗜酸性粒细胞>淋巴细胞>血栓细胞。与已报道的鱼类相比,稀有白甲鱼白细胞的数量明显较高,红细胞数量较多、体积相对较小,可能与其适应流水生活相关。

高寒山区牧草根中丙二醛、渗透调节物、多胺季节动态与抗冻力关系研究

温带地区的高山多年生草本植物可在－３０℃组织结冰状况下生存,然而人们并不了解其抗冻的生理机理。本研究目的拟通过测定自然生境下生长的４种高寒山区禾本科牧草（无芒雀麦（Ｂｒｏｍｕｓ ｉｎｅｒｍｉｓ Ｌｅｙｓｓ．）、花雀麦（Ｂｒｏｍｕｓ　 ｓｉｎｅｎｓｉｓ　 Ｋｅｎｇ．）、垂穗披碱草（Ｅｌｙｍｕｓ ｎｕｔａｎｓ Ｇｒｉｓｅｂ．）、草地早熟禾（Ｐｏａ ｓｐｈｙｏｎｄｙｌｏｄｅｓ　 Ｔｒｉｎ．）根中渗透调节物、膜脂过氧化产物、多胺含量季节变化,以了解他们与牧草抗冻的关系。结果表明,在晚秋（９月１～１５日）牧草根中ＭＤＡ含量增高,尔后下降,冬季保持恒定。总碳水化合物（ＴＮＣ）,可溶性糖、脯氨酸、可溶性蛋白质含量随晚秋气温下降而增加,在１１月达到最高,尔后下降,且持续到翌年春季。随晚秋气温下降从９月到１１月根中多胺含量迅速增加,４种牧草平均增加１８０％,其中亚精胺（Ｓｐｄ）占多胺含量的５３％。在１１月牧草根中多胺几乎完全消失。上述物质在晚秋入冬增加正好与牧草抗冻锻炼时间相吻合,因而是植物抗冻适应的重要生理响应和植物越冬的低温保护物质。他们在降低细胞冰点、防止细胞结冰引起的膜机械伤害,抑制膜脂过氧化保护膜稳定性方面具有重要作用。     

Changes in the blood of Wistar rats in acute poisoning with ethanol and acetaldehyde

1. The purpose of the study was to investigate the effect of ethanol and acetaldehyde on the erythrocyte and leucocyte system of Wistar rats. 2. Administration of the ethanol or acetaldehyde caused a considerable drop in the number of erythrocytes, haemoglobin level and haematocrit value in rats. 3. The mean erythrocyte volume was smaller after only 0.5 hr of exposure to ethyl alcohol. 4. The solutions used caused changes in the leucocyte system expressed in distinct neutrophilic leucocytosis. 5. Changes in the leucogram were reflected in the increase in the leucocyte index. 6. The degree of intensity of changes in both the erythrocyte and leucocyte system point to the greater toxicity of ethyl alcohol intoxication than is the case of acetaldehyde in a toxically corresponding dose (i.e. 0.5 and 5 g/kg body wt respectively).     

Some aspects of haematology of an Indian grass snake Natrix stolata in relation to sex and size.

Studies have been made on the erythrocyte counts per mm3 of blood, total differential leucocyte counts per mm3 of blood, concentration of haemoglobin per 100 ml of blood, haematocrit values and nucleocytoplasmic ratio in a common Indian grass snake, Natrix stolata, in relation to body weight of both the sexes in the same month of the year (during breeding phase). Logarithmic transformations have been used in case of erythrocyte counts and haemoglobin concentrations. From log/log calculation it seems that the correlation between body weight and erythrocyte is more prounounced in females than in males. The concentration of haemoglobin shows a very high degree of correlation in both the sexes. The haematocrit values show a clear trend of increase with increasing body weight in both the sexes. The nucleocytoplasmic ratio does not show much variation in different weight groups whereas in females the variation is well marked in different weight groups and the size of erythrocyte also becomes larger in higher weight groups. In both the sexes the leucocyte counts have been found that along with the increase in body weights, the number of leucocyte increases in juveniles but in adults the leucocyte number decreases with the increasing body weights.     

草鱼外周血细胞数量及其在胁迫或感染下的变化

为了提供可反映草鱼(Ctenopharyngodonidellus)健康状况的血细胞指标的基础数据,研究了4种质量规格组的正常草鱼的外周单位体积血细胞数量,以及分别在硫酸铜或敌百虫处理下和多子小瓜虫感染后的变化。结果表明,1000g组草鱼的单位体积红细胞数显著高于其他3种质量规格组;60g组草鱼的单位体积白细胞数显著低于其他3种质量规格组。硫酸铜或敌百虫处理组的单位体积红、白细胞数显著高于对照组;多子小瓜虫感染组的单位体积白细胞数极显著高于对照组。这里提出一个初步参考指标,60～1000g健康草鱼的红细胞值为1.15×10⁶～3.33×10⁶cells/μL,白细胞值为2.20×10⁵～4.40×10⁵cells/μL。

本文通过显微荧光光度术测量了人工复合三倍体鲤的红细胞及亲本红鲤、红鲫与散鳞镜鲤个体的红细胞和精子的相对DNA含量。结果表明：每一种亲本的精子DNA含量是其红细胞DNA含量的二分之一,人工复合三倍体鲤DNA含量等于三个亲本精子DNA含量之和,为三个亲本血液红细胞DNA含量之和的二分之一。以外周血淋巴细胞制备染色体标本,人工复合三倍体鲤染色体数为150,其亲本红鲤、红鲫和散鳞镜鲤的二倍体染色体数均为100。研究进一步证明人工复合三倍体鲤与二倍体亲本的染色体倍性和相对DNA含量存在着明显的相关性。     

Impact of season on haematological and biochemical parameters of crossbred female calves in hot and humid tropics

The objective of the present study was to assess the impact of season on haematological and biochemical parameters of crossbred female calves. Seven crossbred female calves of 6–12 months of age were selected. The study was conducted in three different spells of 30 days each in pre-monsoon, monsoon and post-monsoon seasons. Ambient temperature (AT), relative humidity (RH) and temperature humidity index (THI) was recorded in all the three seasons. Whole blood was collected for estimation of haematological and plasma was used estimation of biochemical parameters. Highest AT and THI was recorded in pre-monsoon while highest RH was recorded in monsoon. The study revealed that season had no effect on haematological parameters such as total leucocyte, haemoglobin, packed cell volume, mean corpuscular volume, mean corpuscular haemoglobin, mean corpuscular haemoglobin concentration, while total erythrocyte count was significantly lower in monsoon compared to pre and post-monsoon seasons. Glucose and cholesterol were significantly lower in pre-monsoon and monsoon compared to post-monsoon. Glutathione peroxidase activity was significantly higher in pre-monsoon compared to monsoon and post-monsoon. No significant difference between seasons in the concentration of total protein, albumin, globulin and albumin globulin ratio was noticed. The results indicate that hot conditions have profound effect on haematological and biochemical parameters of crossbred calves.     

Some aspects of haematology of a common Indian field rat, Rattus rattus arborious (Linn.) in relation to sex and size.

In the present investigation the studies on erythrocyte and leucocyte counts, haemoglobin concentration, haematocrit values, blood biochemistry of protein, glucose and cholesterol, erythrocyte sedimentation rate, pH value, diameter of erythrocyte and clotting time were made in different sex and size (weight group) of an Indian field rat, Rattus rattus arborious. The number of erythrocyte, haemoglobin concentration, haematocrit values were found to be higher in females than the males, while the number of leucocyte was lower in females in comparison to males. In the biochemical estimation the value of protein in females was high while that of the glucose and cholesterol were lower than that of the males. All the above values showed an increasing tendency with the increase in body weight. pH value, diameter of erythrocyte and clotting time were found to be almost constant in rats of different weight groups and different sex.     

Haematological values during normal reproduction of the maternal and the fetal rabbit

1. Haematological values of non-pregnant/non-lactating, pregnant as well as lactating rabbits and 28-day-old fetuses were measured. 2. The haemoglobin content in does decreased during the observed periods from 122 +/- 8 g/l to 100 +/- 11 g/l. In 28-day-old fetuses it was 85 +/- 0 g/l. 3. The erythrocyte count in 28-day-old fetuses was 2.4 X 10(12)/l. In the does, the erythrocyte count was 5.2 X 10(12)/l in week 4 of gestation. The erythrocyte volume in fetuses was about 45% higher than that of the doe. 4. In fetuses the leucocyte count was approximately one ninth that of the mother in week 4 of gestation (0.41 +/- 0.08 X 10(9)/l vs 3.8 +/- 0.4 X 10(9)/l).     

Regenerative capacity of the spleen in a splenectomized fish, Channa punctatus Bloch, with related investigations into changes in peripheral blood and haematopoiesis

The present investigation has provided evidence by a simultaneous study of the regenerating spleen, peripheral blood and the kidney of the haematopoietic tissue to establish the role of the spleen in the development of circulating blood cells in Channa ( Ophiocephalus ) punctatus Bloch. Regeneration of the spleen after eight to nine weeks of splenectomy was shown to be complete. Weekly observations a fortnight after splenectomy are recorded with reference to spleen morphology and weight, erythrocyte and differential leucocyte counts, haemoglobin content, haematocrit value and related red cell indices (MCV, MCH, MCHC). The results show that splenectomy leads to a macrocytic hypochromic anaemia and leucopenia, resulting in 25% reduction in haemoglobin content and a decrease in leucocyte numbers in five weeks following splenectomy. Thrombocytes and neutrophils show a relative ( P < 0·01) increase. The leucopenia is caused by large and small lymphocytes, eosinophils and basophils whose number was reduced from 50% to 67%.     

Haematology and serum biochemistry of captive unsedated chital deer (Axis axis) in Australia

Haematological and serum biochemical values were measured in blood samples collected over a 12-mo period from 37 unsedated chital deer (Axis axis). Stags and hinds, ranging in age from birth to maturity, were sampled. Haemoglobin, total erythrocyte and haematocrit values were low at birth and sex differences were not apparent in neonates and juveniles, but were in adults. Chital stags had higher erythrocyte parameters (P less than 0.001) and lower erythrocyte indices than hinds, and the total leucocyte count was higher in stags (P less than 0.01). Some parameters (erythrocytes, muscle enzymes, glucose, cortisol) decreased over successive serial sampling. The differential leucocyte count of older stags decreased during the initial handling period. The major rutting period in February and March was characterised by changes in the differential leucocyte count, elevations in serum muscle enzymes, and lower serum cortisol levels. Alkaline phosphatase activity in serum reflected the annual antler cycle of chital stags. Serial sampling over many weeks, either weekly or tri-weekly, produced haematological and biochemical changes in successive samples which may have reflected a reduction in stress and excitement associated with restraint.     

Seasonal variations in the blood constituents of an air-breathing fish, Channa punctatus Bloch

A year long study based on monthly observations on the haematology of female Channa punctatus with respect to haemoglobin, haematocrit values, total erythrocyte and leucocyte numbers together with a differential enumeration of various leucocytes viz. thrombocytes small and large lymphocytes, monocytes, neutrophils, eosinophils and basophils is recorded. The study showed that the total erythrocytic number, haemoglobin and haematocrit values decrease during the breeding time i.e. July to September. The thrombocyte number significantly increased while the neutrophilic number showed a decrease. The physiological significance of these changes is discussed with reference to the available literature.
