Canine herpesvirus is known to be a causal agent of reproduction disorders and diseases of the upper respiratory system. Subclinical infections are also frequently observed. The interest for the virus has risen in recent years especially since latency has been demonstrated and a new vaccine has been developed. In this review article we will successively deal with virus characteristics, epidemiology, pathogenesis, clinical signs, diagnosis as well as therapy and prevention. [less ▲]

OBJECTIVE--To characterize the hemodynamic effects of medetomidine (1 mg/m2 of body surface area; dosage, 39 to 46 micrograms/kg of body weight, IM) and midazolam (1 mg/kg of body weight, i.v.) combined with butorphanol (0.1 mg/kg, i.v.), buprenorphine (10 micrograms/kg, i.v.) or saline solution. Reversibility of these effects by atipamezole (2.5 mg/m2; dosage, 97.5 to 115 micrograms/kg, IM) was evaluated. DESIGN--2 treated groups and 1 control group, without repetition. ANIMALS--15 clinically normal dogs (3 groups of 5). PROCEDURE--Medetomidine was administered at time 0; midazolam and butorphanol, buprenorphine, or saline solution at time 20; and atipamezole at time 60. Heart rate, systemic and pulmonary arterial pressures, central venous pressure, body temperature, cardiac output, and arterial and mixed venous blood gas tensions and pH were measured. Cardiac index, stroke index, systemic and pulmonary vascular resistances, and left and right stroke work indexes were calculated. RESULTS--Body temperature, heart rate, cardiac index, and stroke index were significantly decrease below baseline values in some groups. Central venous pressure, pulmonary capillary wedge pressure, and systemic vascular resistance were significantly increased above baseline in all groups. Arterial and venous PO2 and pH decreased in all groups and PCO2 increased, but these changes were more pronounced when buprenorphine was administered. Arterial pressure decreased after atipamezole administration. CONCLUSION--The combinations seemed to result in cardiorespiratory depressant effects of similar importance and most of these effects, which are related to medetomidine, were reversed by atipamezole.

A technique for laparoscopic intrauterine insemination in bitches is described. During natural estrus, 5 beagle bitches were inseminated and S others were naturally mated (control group) twice at a 48-h interval on Days 3 and S (n = 4) or Days 4 and 6 (n = 6) after the increase in plasma progesterone considered to be indicative of the day of the preovulatory LH peak. All the inseminations were with fresh semen and under general anesthesia. The technique involved the introductions of 1) a Verres needle to insufflate the abdominal cavity by direct punction on the middle line 1 cm over the umbilicus, 2) a laparoscope to visualize the abdominal cavity by a 1 cm puncture on the middle line 1 cm under the umbilicus, 3) a forceps used to manipulate the uterus by a 0.5 cm puncture at 2 to 3 cm lateral to the mammary glands, and 4) an 18-g catheter used to puncture the uterus on the middle line between the 3rd and 5th mammary gland. The uterine body was grasped by the forceps and elevated against the ventral abdominal wall. The 18-g catheter was then inserted through the abdominal wall directly into the uterine lumen, and 1.0 ml of fresh semen containing 250 to 480 x 10(6) spermatozoa/ml was injected. The inseminations resulted in pregnancies in all animals. Litter size was similar in the artificially inseminated and naturally mated bitches (5 +/- 1.8 and 4.8 +/- 1.6 pups per litter, respectively). Bitches in the artificially inseminated group delivered at 65.2 +/- 0.8 d and in the natural mated group at 65.4 +/- 0.5 d after the LH peak. In conclusion, this paper gives the first results of intrauterine laparoscopic insemination in bitches, indicating interesting perspectives for this technique in dog's reproduction. [less ▲]

The cardiovascular and respiratory parameters of eight laboratory beagles were measured before and after the simultaneous injection of medetomidine (40 micrograms/kg bw) and ketamine (5 mg/bg bw). This combination produced a significant alteration in cardiovascular function. The heart rate, the stroke volume and cardiac output decreased while the systemic vascular resistance increased. These effects were attributed principally to the alpha 2 agonist compound combined with the moderate stimulatory effect of ketamine. The respiratory parameters were little affected by this protocol.

Bovine chorionic somatomammotrophin (bCS) was detected in the bovine placenta by using an immunoenzymatic procedure. This hormone appears mainly located in teh binucleate cells of the foetal cotyledons and to a lesser extent in some localized superficial areas of the foetal binucleate cells migrating into the maternal caruncles.
