牛的膈疝缝合术

动物医学进展 1981年第4期 23-24页

作者： J.M.nigam 钟俊才

牛膈疝表现的特征是:反复发生臌气,食欲减退,衰弱,粪便稀软或腹泻和乳产量下降。虽然有几位学者曾对牛膈疝作过报导(Jones 1959;Phablania等1971;Mally和Jayadevappa 1974;Manna(?)ri和Tadkod 1977),但只有少数报导对膈成功的修补是可... 详细信息

A rapid chromatographic method for the determination of six phenolic acids (chlorogenic, ferulic, gallic, p-coumaric, protocatechuic and vanillic acids) by ultra performance liquid chromatography (UPLC), was developed and applied for Brazilian tropical fruits mangaba (Hancornia speciosa Gomes) and umbu (Spondias tuberosa Arruda Camara). A multivariate statistical experimental design was employed to optimize analytical conditions (solvent A, solvent B concentrations and flow rates). Samples were cleaned-up by solid-phase extraction (SPE) with different solvents (methanol and acetone) employing SPE cartridges (amine and octadecyl-silane). The method using dihydrogen potassium phosphate 5 mmoL as solvent A and 8% acetonitrile as solvent B presented limits of detection varying from 14 to 94 ***, limits of quantification from 39 to 277 ***-1 with 2 μL of injection volume while total run time for all six compounds was only 9.6 minutes. Higher recovery was obtained by extraction with methanol-acetone of 69.51% to 72.59% for protocatechuic acid and 69.58% to 126.31% for the chlorogenic acid. The concentrations of chlorogenic, p-coumaric and ferulic acids in mangaba extracts were 113.4, 32.1 and 1.5 μg.g-1, respectively while concentrations of chlorogenic, protocatechuic, gallic, vanillic, ferulic and p-coumaric acids present in umbu fruit were 118.9, 141.3, 3.5, 2.5, 2.2 and 1.8 μg.g-1, respectively.

A rare entity of persistent mullerian duct syndrome usually presents with a common symptom of undescended testis(UDT) or hernia. Male pseudo-hermaphroditism with persistent internal mullerian duct structures can present with a 46, XY karyotype with normal external genitalia and. It arises due to deficiency of antimullerian substance, resulting from reduced production/responsiveness to mullerian duct, leading to persistence of mullerian duct along with normal development of Wolffian duct structures. Presence of mullerian structure prevents testicular descent increasing the risk of testicular vanishing syndrome. The authors here report a case of 16 years old phenotypical male who came with retractile right sided testis and left side UDT in the urology outpatient department. Explorative laparotomy was performed and an ill-defined mass was excised and sent for histopathological examination. Histopathology revealed presence of mullerian structures. The serum testosterone level was normal, buccal smear cytology and karyotyping revealed a 46, XY genotype of the patient.

木糖醇的应用和重要性木糖醇是一种糖醇,一种在自然界中存在的多醇。由于它天然的可利用特性,通常被应用在一些食品中。是一种比普通多元醇甜的啤味剂,是一种糖源。它极好的应用特性是不需要胰岛素来限定其新陈代谢,因此而被作为临床糖尿病人食品中的蔗糖代用品。而且它的代谢不需要葡萄糖—6—磷酸脱氢酶,对于葡萄糖—6—磷脱氢酶不足的人来说是一种理想的甜味剂。木糖醇最显著的特点是一种抗龋齿甜味剂。
