Constipation is a symptom of a problematic, non-smooth and irregular defecation process. While laxative is a substance that stimulates intestinal peristalsis as a reflex of direct stimulation of the intestinal wall that can cause or facilitate defecation. This study aimed to determine the ethanol extract of the leaves of Gynura procumbens (L.) Merr. effect as a laxative in white male mice induced by loperamide. The methods used for laxative testing are defecation patterns and intestinal transit methods. The parameters observed included frequency of defecation, stool consistency, stool weight every 30 minutes for 4 hours, and the length of the activated carbon in the mice's intestine. The extract was administered orally at a dose of 75 mg/kg BW, 150 mg/kg BW and 300 mg/kg BW, as a comparison used negative control (Na CMC). From the results of the study, it was found that the administration of ethanol extracts of Gynura procumbens (Lour.) Merr. leaves at the dose of 150 mg/kg BW gave laxative activity to white male mice (P <0.05).

Summary5,-5'-diphenyl-2-thiohydantoin (DPTH) is an effective inhibitor of thyroxine (T4) stimulation of α-glycerophosphate dehydrogenase in rat liver mitochondria. Because this finding indicated a possible tool for future study of the mode of action of thyroxine, the ultrastructural and biochemical effects of DPTH and/or thyroxine on rat liver mere investigated.Rats were fed either standard or DPTH (0.06%) diet for 30 days before T4 (250 ug/kg/day) was injected. Injection of T4 occurred daily for 10 days prior to sacrifice. After removal of the liver and kidneys, part of the tissue was frozen at -50°C for later biocheailcal analyses, while the rest was prefixed in buffered 3.5X glutaraldehyde (390 mOs) and post-fixed in buffered 1Z OsO4 (376 mOs). Tissues were embedded in Araldlte 502 and the sections examined in a Zeiss EM 9S.Hepatocytes from hyperthyroid rats (Fig. 2) demonstrated enlarged and more numerous mitochondria than those of controls (Fig. 1). Glycogen was almost totally absent from the cytoplasm of the T4-treated rats.

Insect molting and metamorphosis are elicited by a class of polyhydroxylated steroids, ecdysteroids, that originate in the prothoracic glands (PGs). Prothoracicotropic hormone stimulation of steroidogenesis by the PGs at the cellular level involves both calcium and cAMP. Cell-to-cell communication mediated by gap junctions may play a key role in regulating signal transduction by controlling the transmission of small molecules and ions between adjacent cells. This is the first report of gap junctions in the PGs, the evidence obtained by means of SEM, thin sections and freeze-fracture replicas.
