中草药外用治疗肉犬皮肤真菌病

2001年6月8日,互助县威远镇崖头村汪某饲养的肉犬因患皮肤病前来邀诊.主诉:其家一犬 (后共发病5只)不断磨擦和啃咬身体,并伴有阵发性瘙痒症状,2天后患犬背部、腹部、颈部、耳后等部位被毛脱落,皮肤发红,肿胀,出现水泡,龟裂,流淡黄色液体,食欲减退, 变瘦,严重影响犬的生长发育和皮张质量.笔者采集病料送检见有大量真菌,于是确诊为真菌引起的过敏性皮炎.椐此采用中草药方对患犬进行药液涂擦患部治疗,收到了很好的效果 .

Experimental toxoplasmosis in pregnant bitches.

Three Toxoplasma gondii free bitches (No. 3-5) were fed 15000 sporulated T. gondii oocysts at 56, 40 and 32 day of gestation and the outcome of the pregnancy was monitored. Two of the three dogs infected during pregnancy showed evidence of congenital infection and one aborted. Two control bitches not fed oocysts delivered eight uninfected healthy pups. This study demonstrated that T. gondii can be congenitally transmitted in dogs when bitches are infected during pregnancy.     

Serum concentrations of leptin in pregnant and non-pregnant bitches

Leptin regulates body weight and several physiological processes including reproduction. We evaluated the circulating levels of leptin in pregnant and non-pregnant bitches as well as their correlation with body weight, food intake and number of foetuses. Nineteen healthy German shepherd bitches were used and divided in two groups (pregnant n = 12 and non-pregnant n = 7). Blood samples were collected every 15 days starting from ovulation (Day 0) throughout pregnancy (pregnant group, P) or throughout luteal phase (non-pregnant group, NP) In pregnant bitches, leptin concentrations increased from the day of ovulation (1.32 ± 0.06 ng/ml) up to day 45 (1.51 ± 0.06 ng/ml; p < .01) and returned to baseline values from day 60 post-ovulation. In non-pregnant bitches, leptin concentrations remained constant throughout the whole observation period (estimated marginal mean ± SE=1.33 ± 0.38 ng/ml). Pairwise comparisons showed significant differences between P and NP at day 45 post-ovulation (p < .05). Multivariable models indicated that, controlling for time and litter size, there was a positive relationship between leptin concentration and BW (p < .05) although Pearson coefficients showed that the correlation between BW and leptin was only significant in NP animals at day 45 (r = 0.76, p < .05). The multivariable approach also suggested that, holding BW and time constant, leptin concentrations tend to increase as the number of puppies increased (p = .06). Our study supports indirectly the contribution of the feto-placental unit to the circulating maternal leptin concentration.     

Attempted oestrus induction in four bitches using pregnant mare serum gonadotrophin

Two juvenile (9 months) and two adult (3 years) beagle bitches were injected with five doses (250 i.u. per dose) of pregnant mare serum gonadotrophin (PMSG) on alternate days. Plasma oestrogen concentrations rose in all bitches. In one adult bitch plasma progesterone concentrations remained basal and no signs of oestrus were shown; in the other there was a slight elevation of circulating progesterone values and she showed oestrus but did not conceive. Both the young bitches came into heat and had multiple ovulations, producing very high plasma progesterone concentrations. One of them conceived, and at laparotomy on the thirty-sixth day after the first mating seventeen conceptuses were seen; 14 days later ovarohysterectomy was performed and only five foetuses remained in the uterus.

Experimental transplacental transmission of canine herpesvirus in pregnant bitches during the second trimester of gestation

The effects of canine herpesvirus (CHV) on fetuses were studied after IV inoculation of pregnant bitches in the 2nd trimester of gestation. Cesarean sections were performed on 2 bitches that were inoculated with CHV on the estimated 30th day of gestation. Bitch M-1 had 2 mummified fetuses and bitch M-2 had 4 mummified and 2 dead fetuses and 3 live-born pups. Infection by CHV was confirmed histopathologically by the presence of focal areas of necrosis associated with intranuclear inclusion bodies in heart muscle sections of 1 dead fetus; CHV was not recovered from other organs. Abortion occurred between the 2nd and 3rd week after inoculation of another pregnant bitch inoculated with CHV on the estimated 30th day of gestation. Two bitches inoculated with CHV on the estimated 40th day of gestation gave birth prematurely to 10 pups. The detection of characteristic herpesviral lesions in various organs and the reisolation of CHV from the liver, spleen, kidneys, and lungs of premature pups indicated CHV infection. Transplacental infection of fetal pups by CHV resulted in their death and subsequent mummification. It appears that abortion and premature birth also may occur in pregnant bitches infected during the 2nd trimester of gestation.
