Lymphoglandular Complexes in Proximal Colon of Buffalo Calves (Bubalus bubalis) Complejos Linfoglandulares en Colon Proximal de Terneros de Buffalo (Bubalus bubalis)

چکیده
The present study was conducted on six healthy early neonatal and six prepubertal buffalo calves to study the location, gross morphology, histomorphology and histochemistry of lymphoglandular complexes in proximal colon. In very proximal part of colon of buffalo calves, an irregular oval mucosal lymphoid patch was found grossly as a proximal colon (PC) patch. Histologically, in proximal colon patch of early neonates (3-4 weeks), an extensive invasion of mucosal glands was observed towards lymphoid nodules that were present in submucosa. The structure as a whole thus formed a complex known as lymphoglandular complex (LGC). Large number of such complexes i.e., LGCs were observed in submucosa of proximal colon at this age. At some places, invasion of mucosal glands into lymphoid tissue was restricted to superficial layer of complexes, with the lymphoglandular complexes opening directly into the lumen but some were deep seated. However, by the age of 6 months in buffalo calves i.e., prepubertal period, LGCs were reduced and were present in single layer within the submucosa of the proximal colon. Moreover, some of LGCs were completely encapsulated by their own lamina muscularis mucosae. But some of the complexes still had their mucosal openings into lumen while others had lost their connection with tunica mucosa. Histochemically, the glands that were observed within LGCs contained mucosubstances, glycogen, mucopolysaccharides, and mucin. However, lipids were present around the lymphocytes observed towards the periphery of these LGCs.

Male Indian buffalo (Bubalus bubalis) calves were submitted to Schistosoma mansoni infection by percutaneous, oral and subcutaneous routes. No worms or eggs were found in four of the animals tested. Bubalus bubalis appears to be refractory for S. mansoni.

Pharmacokinetics of ceftriaxone was studied in buffalo calves (Bubalus bubalis) after single intravenousand intramuscular administration of 10 mg/kg body weight. The drug concentrations in plasma samples weremeasured by high performance liquid chromatography with UV detection. Following intravenousadministration, the drug was rapidly distributed (Cpo: 106.5 ± 9.64 μg/ml; t1/2α: 0.09 ± 0.01 h; V...

Population characteristics, breeding structure, and sources of mortality of wild water buffalo Bubalus bubalis were studied in Kosi Tappu Wildlife Reserve, a small reserve located in the southeastern lowlands of Nepal, during 1987 and 1988. Comparisons with an earlier census indicated that the population was growing over a 12-year time interval. However, observations on the physical nature of t...
