ABSTRACT
A veterinary education twinning project between Chattogram Veterinary and Animal Sciences University (CVASU) and Tufts Cummings School of Veterinary Medicine (TCSVM) was supported by the World Organisation for Animal Health (OIE) to align CVASU's veterinary curriculum with OIE's recommended Core Curriculum and Day 1 Competencies. The major objectives were curriculum development with improvement to the internship program, introduction of problem-based learning (PBL), and implementation of continuing education (CE). Major activities to achieve these objectives involved several workshops and seminars at CVASU and establishing student exchange and CVASU faculty training programs. Major accomplishments were (a) implementation of a revised Doctor of Veterinary Medicine (DVM) curriculum at CVASU aligned with the OIE-recommended curriculum and Day 1 Competencies; (b) incorporation of PBL into the curriculum and development of 23 PBL cases relevant to Bangladesh-specific diseases; (c) improvement of the internship program by including Day 1 Competencies; (d) development and implementation of 11 structured CE sessions including hands-on training; (e) improvement of curriculum, teaching, and clinical training at CVASU following training of CVASU faculty and students at TCSVM; and (f) three peer-reviewed publications from summer research projects by TCSVM students at CVASU. The twinning project allowed CVASU to improve its DVM curriculum by aligning with OIE's recommended curriculum and Day 1 Competencies. The impact of the project went beyond CVASU as evidenced by other veterinary schools adopting the CVASU curriculum and PBL, veterinary school deans engaged in improving veterinary curriculum and clinical training, and implementation of a national CE program for veterinarians.

The effect of guanosine 3',5'-cyclic monophosphate (cGMP) on hepatic bile formation was studied in isolated perfused rat livers and rat hepatocytes. Studies in isolated perfused rat livers showed that infusion of 8-bromoguanosine 3',5'-cyclic monophosphate (8-BrcGMP, 3 micromol/min or 100 microM) 1) increased bile flow without affecting biliary excretion of simultaneously infused taurocholate, 2) increased biliary concentration and excretion of HCO3(-) but did not affect biliary excretion of glutathione, and 3) increased net perfusate H+ efflux without affecting hepatic O2 uptake. Studies in isolated rat hepatocytes showed that 1) 8-BrcGMP increased intracellular pH in the presence (but not in the absence) of extracellular HCO-3, and effect inhibited by 4,4' -diisothiocyanostilbene-2,2'-disulfonic acid and Na+ replacement, 2) 8-BrcGMP did not affect taurocholate uptake and intracellular [Ca2+], and 3) bile acids, like ursodeoxycholate and cholate, did not increase cellular cGMP. Taken together, these results indicate that cGMP stimulates bile acid-independent bile formation, in part by stimulating biliary HCO3- excretion. cGMP may increase HCO3- excretion by stimulating sinusoidal Na+ - HCO3- cotransport, but not Na+/H+ exchange. cGMP, unlike adenosine 3',5'-cyclic monophosphate, may not regulate hepatic taurocholate transport, and bile acid-induced HCO3- rich choleresis may not be mediated via cGMP.
