Surgery of hepatic cysts in a cat.

A 2-year-old female Japanese domestic cat weighing 3.6 kg was presented due to marked abdominal distention and was diagnosed as hepatic cyst. The bile acid concentration of the hepatic cyst was as low as the serum bile acid concentration. The membrane of the cysts was excised from the edge of the compressed hepatic tissue and no other surgical manipulation was performed. This surgical procedure is simple and quick compared to hepatic lobectomy, however, it is necessary to evaluate the fluid of the cyst before performing this procedure.     

Suppurative Inflammation of Apocrine Sweat Glands (Suppurative Hidradenitis) in the Dog: A Retrospective Clinicopathological Analysis of 100 Cases

Résumé— Une analyse rétrospective clinicopathologique a été menée chez 100 chiens présentant une hydradénite suppurative diagnostiquée par biopsie cutanée. Aucune prédisposition d'âge, de race ou de sexe n'a été mise en évidence. Tous les chiens présentaient cliniquement une folliculite bactérienne, ou une furonculose, ou les deux, qu'elle soit primaire ou secondaire à d'autres dermatoses. Aucene lésion clinique n'était pathognomonique d'hidradénite suppurative. Chez 73 chiens, l'hidradénite suppurative était associée microscopiquement à des degrés variables d'inflammation du follicule pileux. Chez 27 chiens, l'hidradénite suppurative était la seule évidence histologique d'inflammation annexielle. L'observation histopathologique d'hidradénite suppurative suggère l'existence sur le plan clinique d'une folliculite bactérienne, d'une furonculose, ou des 2. [Scott, D.W.

Resumen— Se llevó a cabo un estudio clinicopatológico retrospectivo en 100 perros con hidradenitis supurativa diagnosticada mediante biopsia cutánea. No se detectó predominancia alguna de raza, sexo o edad. A todes los perros se les habia diagnosticado clinicamente foliculitis o furunculosis bacteriana, o ambas, ya sea de forma primaria o secundaria a otras dermatosis. No se encontraron lesiones clinicas especificas indicativas de hidradenitis supurativa. En 73 animales, la hidradenitis supurativa estaba asociada con varios grados de inflamación folicular a nivel microscópico. En los 27 casos restantes, los anejos presentaban unicamente hidradenitis supurativa. La presencia de hidradenitis supurativa a nivel microscópico sugiere la existencia de foliculitis o furunculosis bacteriana clinicas, o de ambas. [Scott, D.W. Suppurative inflammation of apocrine sweat glands (suppurative hidradenitis) in the dog: a retrospective clinicopathological analysis of 100 cases (inflamación supurativa de las glándulas sudoriparas apocrinas (hidradenitis supurativa) en el perro: estudio clinicopatológico retrospectivo de 100 casos). Abstract— A retrospective clinicopathological study was conducted on 100 dogs with suppurative hidradenitis as determined by skin biopsy. No apparent age, breed, or sex predilections were recognized. All dogs had been given a clinical diagnosis of bacterial folliculitis, furunculosis, or both of these, whether primary or secondary to other dermatoses. There were no clinical lesions that uniquely suggested the presence of suppurative hidradenitis. In 73 dogs, suppurative hidradenitis occurred in conjunction with varying degrees of hair follicle inflammation microscopically. In 27 dogs, suppurative hidradenitis was the only histological evidence of adnexal inflammation. The histopathologic finding of suppurative hidradenitis suggests the existence of clinical bacterial folliculitis, furunculosis, or both of these.     

Efficacy of the morantel sustained release trilaminate matrix against gastrointestinal nematodes in beef calves

The effectiveness of the morantel sustained release trilaminate (MSRT) in controlling gastrointestinal nematodes through a grazing season was evaluated using 60 yearling beef stocker calves randomly divided into 2 groups of 30 animals each. In April 1985, the calves comprising the treatment group each received an MSRT designed to release morantel tartrate continuously for 90 days while those of the control group remained unmedicated. All animals were weighed and samples of rectal feces were taken at 14-day intervals, beginning on Day 0, until trial termination (Day 168). At trial termination, 10 control and 10 treated calves were necropsied for recovery of gastrointestinal nematodes. Three sets of parasite-na?ve tracer calves were utilized to evaluate the initial, interim and final levels of pasture contamination by nematode larvae. Overall, the use of the MSRT resulted in a 75.5% reduction (P less than 0.001) in output of nematode eggs from the principals, an 81.8% reduction (P less than 0.001) in numbers of gastrointestinal nematodes in principals (at trial termination), and a 96.9% reduction (P less than 0.05) of pasture larval nematode contamination (as indirectly indicated by parasite burdens in tracer calves). The mean weight advantage of treated calves was 16.6 kg per head (P less than 0.001).     

Effect of Completion of Vernalization on Generative Development of Winter Rape (Brassica napus L. var. oleifera) Plants

Germinating seeds and young plants of winter rape var. Górczañski were vernalized for 56–63 days under conditions of 9-hour day, at the temperature 2 and 5 °C and in continuous darkness at the temperature 2 °C. After vernalization the plants grew under conditions enabling to complete vernalization: in a glass-house at the temperature day/night 15/10 °C and in semi natural conditions of open vegetation hall in the period from June till August. After sub-optimal vernalization further growth of the plants at lowered temperature increased its effectiveness (completion of vernalization). Depending on the degree of the vernalization of the plants the completion of their vernalization was both obligatory, i.e. conditioning the acquisition of the ability of generative development, and facultative i.e. accelerating this development. It has been demonstrated that the population of plants of the examined variety is strongly differentiated not only with respect of vernalization requirements in the particular plants, but also what regards the effectiveness of vernalization completion. New observations have been made indicating that the mechanisms controlling the successive phases of generative development, i.e. phase of forming flower buds and the flowering phase are not identical which may be interpreted as indicating that the "flowering factor" is polymorphous.     

Analysis of Growth and Productivity of Indian Mustard (Brassica juncea) in Relation to FYM, Nitrogen and Source of Fertilizer

A field experiment was conducted during the winter seasons of 1992–93 and 1993–94 at Anand to study the effect of FYM, nitrogen and source of fertilizer on growth and yield of mustard [ Brassica juncea (L.) Czernj & Cosson]. The results showed significant variation in leaf area index (LAI), crop growth rate (CGR), dry matter production and seed yield. The direct effect of farmyard manure (FYM) was conspicuous in improving the growth of mustard. FYM application at 10 tonnes ha⁻¹ significantly increased the LAI, CGR and dry matter accumulation per plant at almost all the stages during first year study (1992–93) and in pooled analysis. Similarly, nitrogen application registered maximum LAI, CGR at 75 kg level and RGR and NAR at 50 kg level at almost all the during both years. Sulphur carrying source (Ammonium sulphate plus single super phosphate) increased all stages growth characters. Maximum dry matter accumulation per plant and seed yield were recorded with highest levels of FYM (20 tonnes ha⁻¹), N (75 kg ha⁻¹) and source having S. Seed yield was strongly associated with LAI and dry matter accumulation per plant at all the stages.     

Differentiation and transplantation antigens on the surface of mononuclear cells of cattle, horses and dogs

The determination of differentiation and transplantation antigens will be of growing importance in immune diagnosis for individual animals as well as for breeding purposes in populations. Differentiation antigens characterize subsets of cell populations and indicate their functional capacity while transplantation antigens represent markers of individuals of a species. Occurrence and significance of these antigenic systems are briefly reviewed.     

Interferon in sheep]

There is only limited information on sheep interferon available. Recent publications have reported on: 1. an interferon (IFN) alpha subtype, which is secreted by the fetal trophectoderm into the lumen of the uterus between the 10th and 21st day of gestation. It was therefore named ovine trophoblast protein (oTP-1), and is responsible for signalling pregnancy to the ewe via high affinity receptors in the endometrium. It is thought that oTP-1 acts by directly influencing prostaglandin metabolism. 2. the role of lentivirus-induced interferon (LV-IFN) in the pathogenesis of Maedi/Visna. The results indicate that LV-IFN limits viral replication and therefore contributes to virus persistence and is also responsible for a chronic inflammatory process. 3. the mitogen- or antigen-dependent induction of ovine interferon gamma (IFN gamma) and its characterization.
