Intramuscular fat and collagen content are major factors affecting beef quality, but mechanisms regulating intramuscular adipose and connective tissue deposition are far from clear. Japanese Wagyu cattle are well known for their extremely high marbling. The objective of this study was to evaluate intramuscular fat (IMF) and collagen deposition in the muscle(More)
Beef cattle are raised for their lean tissue, and excessive fat accumulation accounts for large amounts of waste. On the other hand, intramuscular fat or marbling is essential for the palatability of beef. In addition, tender beef is demanded by consumers, and connective tissue contributes to the background toughness of beef. Recent studies show that(More)
BACKGROUND Thin glomerular basement membranes may be an important cause of microscopic haematuria. Unfortunately measurements are often not made because of the complicated methods currently employed. METHODS A simplified method of measurement of glomerular basement membrane thickness, involving only 16 selected measurements on a single glomerulus, was(More)
The methanolic extract of leaves of Lippia nodiflora Linn. was tested for its anti-inflammatory and antinociceptive activities. The extract showed a significant (P < 0.001) anti-inflammatory activity comparable to phenylbutazone against carrageenin-induced paw edema in rats and a significant (P < 0.001) antinociceptive activity comparable to diclofenac(More)
The purpose of the present investigation was to study the histogenesis of the mucoepidermoid carcinoma of the salivary glands. Eleven cases of mucoepidermoid carcinoma of the minor salivary glands and five of the major glands were extensively studied employing immunohistochemical and fluorescent microscopic techniques. Both the intermediate cells and the(More)
Calcium-channel antagonist drugs are prescribed widely for angina and hypertension. A limiting side effect is edema, which can make heart failure worse. We show that nifedipine, a dihydropyridine-type calcium-channel antagonist, can increase vascular permeability in rat skeletal muscle and skin when injected locally. In nifedipine-injected cremaster muscle,(More)
Acute appendicitis is the commonest causes of emergency surgery, having worldwide prevalence and affects all age groups. The etiology of acute appendicitis is multi-factorial and the pathology is most likely the obstruction of the lumen of the appendix. Acute appendicitis due to helminthes and protozoan infection is quite rare. Other unusual findings in(More)
The histopathological and topographical alterations occurring during the early stages of chemical carcinogenesis in the hamster cheek pouch using 7,12-dimethylbenz (alpha) anthracene (DMBA) were studied by light and scanning electron microscopy. At the scanning electron microscopic level, cellular overlapping and mild disturbance of intercellular bridges(More)
Chronic immune complex glomerulonephritis was induced in a group of New Zealand white rabbits by daily intravenous injections of cationized bovine serum albumin (cBSA). The animals were serially killed and renal tissue was embedded in the hydrophilic resin Lowicryl K4M for immunoelectron microscopy. The results demonstrate the progressive deposition of(More)
