Chinese Journal of Immunology 1985;0(05):-
We studied the effects of oxymatine,an alkaloid from Sophra Flavesens Ait,on human andmouse's lymphocytes' cytoplasmic free calcium,calium uptaking,cAMP & cGMP level.Theresults show that:(1).Oxymatrine can raise the cytoplasmic free calcium.(2).It can also de-crease the cAMP level of PHA preactivated human tonsillar lymphocytes (3).It has no effect oncGMP level of lymphocyte.(4).It has no effect on the calcium uptaking.Combined with ourprevious report,we think that oxymatrine may influence cells' [Ca++] and cAMP level via af-fecting cell membrane.
2.Antibody mediated sperm phagocytosis by rat peritoneal macrophages
Chinese Journal of Immunology 1985;0(03):-
More recently, a high incidence of antisperm antibodies in men and women with unexplained in fertility has been reported by many authors. However, the antisperm antibodies may play a role in mediating in fertility by interacting with sperm. The effect of antisperm antibodies on the phagocytosis of rat peritoneal macrophages were studied in vitro. The results indicated that opsonization of rat sperm by rabbit anti-rat sperm antibodies increases both the percentage of phagocytosis and phagocytic index apparently. The engulfed sperm when observed by SEM were bended and wrapped up. It seems likely that antisperm antibodies enhanced phagocytosis by macrophages may take part in the antisperm immune responses.

Thirty three tibial fractures treated with interlocking intramedullary nail(IMN) were reviewed. Of all the patients, 16 were fixed with reamed IMN, and 17 with nonreamed IMN. There were 22 closed and 11 open fractures. Twenty seven patients were followed up for an average of 17.9 months (4 to 31 months). Of all the patients, 22 healed in 6 months, delayed healing occurred in 1,and in 1 the distal locking screw was broken. In the close fractures, the mean time from fracture to operation was 3.55 days (from the injury day to 27 days) , and in the open fractures operation was all done on the day of injury. Nonreamed IMN was used in 12 closed fractures (54.5%, 12/22 ) , and reamed IMN was used in 4 open fractures (36.3%, 4/11). There was no postoperative compartment syndrome or infection. The interlocking intramedullary pin is indicated for the tibia fractures, and early operation is feasible . The nonreamed interlocking intramedullary pin is suitable for open fractures and multi injuries.

The microvasculature of the rabbit right ventricle was studied by the method of vascular corrosion cast and scanning electron microscopy. In the endocardium could be seen thin and sparse capillary network i. e. subendothelial capillary network formed by the branches of the arterioles passing through myocardium. In the myocardium, arteriole and its branches distributed in certain area. Sphincters could be seen in the beginning of the arterioles. Capillaries of the papillary muscle in right ventricle were parallel to muscle bundle and were thinner and sparser than those of the papillary muscle in left ventricle. Venous system in right ventricle wall was similar in architecture to that in left ventricle, postcapillary venule joined its corresponding venule in a "turnip root" like pattern. No A-V anastomosis could be seen, yet thebesian vessels and myocardial sinusoids directly opened into ventrical chamber could be found.

Objective To explore the outcome and diagnostic methods of umbilical cord winds of the perinatal. Methods Retrospective analysis of 2350 cases of umbilical cord winds in our hospital was conducted. We selected 2400 cases as control. We calculated both the incidence rate of cesarean section, fetal distress and neonatal hypoxic - ischemic encephalopathy. Results Umbilical cord winds accounted for 20.1 percent of the total number of deliveries in the same period. The incidence rate of fetal distress and cesarean section was significantly high. Bsound ultra was 98.9% diagnosis. The electronic fetal care was 99.7% in diagnosis. Color Doppler ultrasound was 100% in diagnosis. Conclusion Umbilical cord winds is a common complication of pregnancy, and decision is also an important factor for delivery mode. Umbilical cord winds will increase obviously in the incidence of fetal distress and perinatal morbidity. The main method for prenatal diagnosis is the color Doppler ultrasound examination, such as B - and E - fetal care. Color Doppler ultrasound technique is the best way for non - invasive is observation of intrauterine blood circulation changes. In helpful for the judge of the progress and outcome of pregnancy, fetal growth and development of the situation.

Objective:To optimize the compatibility conditions of erigeron injection and study the stability after compatibility. Methods:An orthogonal test was employed using the quantity of insoluble particles and the content of rutin as the indices and tempera-ture, solvent and solvent amount as the influencing factors. The results were comprehensively analyzed. According to the results of the orthogonal test, three batches of samples were prepared and observed the stability in 24 hours, including the changes in the number of insoluble particles, pH and total flavonoid content. Results:The optimal compatibility conditions were as follows:the temperature was 25℃, and 250 ml 0. 9% sodium chloride injection was used as the solvent. The appearance and the insoluble particles showed no sig-nificant changes in 24 hours. The total flavonoid content was also stable in 4 hours, but decreased to some extent after then. Conclu-sion:At the clinical dose, erigeron injection in 250 ml 0. 9% sodium chloride injection can keep stable in 4 hours.

Objective To investigate the therapeutical effect and mechanism of tiotropium bromide in patients with stable phase midrange and severe chronic obstructive pulmonary disease (COPD). Methods Seventy-eight patients with stable phase midrange and severe COPD were selected, and they were divided into observation group (40 cases) and control group (38 cases) according to treatment method. All patients were given conventional treatment. The patients in observation group were given tiotropium bromide, and the patients in control group were given terbutaline according to the needs for 12 weeks. The changes of dyspnea, 6 min walking distance, pulmonary function, leukotrienes C4 (LTC4), interleukin-8 (IL-8), tumor necrosis factor-alpha (TNF-ɑ) before and after treatment, and drug adverse reaction were observed. Results The dyspnea score after treatment in observation group was significantly lower than that in control group:(2.9±0.5) scores vs. (3.5±0.7) scores, 6 min walking distance in observation group was significantly longer than that in control group: (427.67±70.36) m vs. (365.41±61.42) m, forced expired volume in 1 second (FEV1) and FEV1/forced vital capacity in observation group were significantly higher than those in control group:(1.76±0.89) L vs. (1.29±0.53) L and (67.43±9.52)%vs. (56.32±8.51)%, LTC4, IL-8 and TNF-αlevels in observation group were significantly lower than those in control group: (397.41± 198.57)μg/L vs. (1 181.95±207.54)μg/L, (434.81±176.05) ng/L vs. (823.37±165.43) ng/L and (0.15±0.02) ng/L vs. (0.25 ±0.02) ng/L, there were significant differences ( P<0.01). Pearson correlation analysis result showed that serum LTC4 level was negatively related to FEV 1 (r=-0.578, P=0.024);and the serum IL-8 level was negatively related to FEV1 (r=-0.542, P=0.019). There was no obvious drug adverse reaction in the two groups. Conclusions Tiotropium bromide can significantly improve the clinical manifestations in patients with COPD. Tiotropium bromide may take effects by blocking various inflammatory factors release in the stable phase of COPD.

Anopheles minimus was infected with Plasmodium yoelii yoelii under adequate condition. The malaria parasite could develop normally and produce mature oocysts containing sporozoites. Large numbers of free active sporozoites were found in the haemocele but most of them failed to penetrate into the mosquito's salivary glands. Thus the sporogonic cycle of the parasite could not be completed.But in one mosquito, a few sporozoites were found in its salivary glands. It seems that there is an individual difference in the susceptibility of the mosquitoes and this throws some light on the possibility of selecting a susceptible strain of A. minimus to establish the A. minimus-P. yoelii system for malaria research.

Objective To study the altered expression of dopamine transporter (DAT) in substantia nigra and striatum in postmortem human brain of Parkinson’s disease (PD). Methods Immunoautoradiography was used to reveal DAT distribution in postmortem human brain. Results Strongly labeling signal of DAT was mainly found in the substantia nigra, the putamen and the caudate nucleus in controls. In contrast, it was drastically reduced in the putmen and the dorsolateral caudate nuclus in PD brains, but the ventromedial part of the caudate nucleus showed a significant sparing adjacent to the border of the lateral ventricle. In the substantia nigra, the ventral and the lateral parts of the substantia nigra showed an obvious decreasing of DAT and the reducing degree of DAT labeling signals in those regions is smaller than that in the putamen and the caudate nucleus. Quantitative analysis revealed that 90.9% and 66.7% of the labeling intensity of DAT were decreased in the putamen and the caudate nucleus as comparing with the corresponding controls respectively (P
