1. The rate of heart beat increased with temperature and was three times as high in the active as in the inactive animal. 2. The rate of shell valve movement rose and the rate of heart beat fell when the foot was extended. 3. The rates of heart beat and shell valve movement decreased when the water was saturated with carbon dioxide. This heart response remained when the visceral ganglion was de...

An extract of ovine and bovine pineal glands (labeled Precipitate II) has previously been shown to possess lipolytic activity on rabbit adipose tissue. This extract also causes darkening of the frog’s skin in vivo and in vitro. Both lipolytic and melanotropic activities are abolished by trypsin and chymotrypsin. Fractionation of ovine pineal Precipitate II by the sequence, chromatography on die...

The objective of this study was to determine the effects of water regime/soil condition (continuous flooding, saturated, and aerobic), cultivar ('Cocodrie' and 'Rondo'), and soil texture (clay and sandy loam) on rice grain yield, yield components and water productivity using a greenhouse trial. Rice grain yield was significantly affected by soil texture and the interaction between water regime ...

Purpose: To investigate potential analgesic and antioxidant properties in the ethanolic root extract of Clerodendrum viscosum Vent. Methods: Phytochemical analysis of the ethanolic root extract was evaluated using standard procedure. Analgesic activity test was carried out by acetic acid induced writhing in mice model. The antioxidant property of the plant extract was assessed by DPPH (1, 1-dip...

BACKGROUND The Seven Countries Study has shown that population mortality rates for various chronic diseases are related to diet and smoking. This paper addresses the associations between diet, smoking and 25-year all-cause mortality. METHODS Baseline surveys were carried out between 1958 and 1964 on 12,763 middle-aged men constituting 16 cohorts in seven countries. In 1987/88 equivalent food ...

Many properties of chemicals depend on their streochemistry. Among these, the effects of streoisomerism on percutaneous absorption of drugs, which is subject of the present investigation, is not well studied yet. In this study, tretinoin (TT) and isotretinoin (ITT) (geometric isomers) were chosen and their permeations (alone or in the presence of each other) through enhancer-treated excised ...

Nowadays, uncontrolled and frequent use of antibiotics may cause emergence of microbial resistanceamong pathogenic agents. Therefore, the use of new synthetic and natural antimicrobial compounds isinevitable. One source of natural compounds in this respect comes from plants. The purpose of this study was to examine the antibacterial effects of peel extracts from sour and sweet pomegranate. Meth...

OBJECTIVE To determine the vision-related quality of life (VR-QOL) after surgery for macula-off rhegmatogenous retinal detachment (RRD) in relation to visual acuity, contrast acuity, and color vision. METHODS In a prospective observational study, we included 55 patients with a macula-off RRD. Best corrected visual acuity (BCVA), color vision (saturated and desaturated color confusion indices ...
