Potential Galactagogue Effect of Tri-Than-Thip Remedy on Milk Synthesis in Lactating Rats: Impact on Milk Production-Related Parameters.

Herbal galactagogues have been widely used as a treatment for postpartum hypogalactia due to the potential side effects associated with pharmacological therapy. Tri-Than-Thip (Tri-TT) is a Thai herbal medicine remedy that contains three main components: Cassia fistula, Pithecellobium dulce, and Ficus benjamina. These components are believed to have properties that contribute to milk production. However, despite the traditional use of Tri-TT, there is a lack of academic evidence supporting its efficacy in enhancing milk production. Therefore, the purpose of this study was to investigate the effect of Tri-TT on milk production and determine if it has a galactagogue effect. The weight suckle weight model was used to determine total milk production in lactating rats, while histological analysis was performed to assess the alveolar diameter of the mammary gland. The findings of this study revealed a significant increase in total milk production among lactating rats treated with 500 mg/kg of Tri-TT, compared to the control group. Furthermore, both the Tri-TT and Domperidone-treated groups exhibited a larger alveolar diameter of the mammary gland in comparison to the control group. In summary, these findings provide supportive evidence for the galactagogue activity of Tri-TT. The observed enhancement in milk production may be associated with Tri-TT could potentially be attributed to its ability to widen the alveolar diameter of the mammary gland, thereby facilitating increased milk volume.

Decreased body-fat accumulation and increased vasorelaxation to glyceryl trinitrate in middle-aged male rats following six-weeks consumption of coconut milk protein

Abstract We investigated whether coconut milk protein (CMP) contributes to the beneficial effects of coconut milk consumption on cardiovascular health markers previously found in middle-aged rats. CMP was isolated and precipitated from dried fresh coconut milk, then gavaged (1 g/kg) to middle-aged male rats for six weeks; control rats received distilled water. Compared to controls, CMP caused decreased body fat and lipid accumulation in liver cells and the platelet count. CMP did not affect basal blood pressure or heart rate in anesthetized rats. Vascular responsiveness to phenylephrine, DL-propargylglycine (PAG), acetylcholine or sodium nitroprusside was unaffected, but vasorelaxation to glyceryl trinitrate (GTN) increased. Effects of ODQ on vasorelaxation to GTN were similar in both groups. Expression of blood vessel eNOS, CSE and sGC was normal. The cyclic guanosine monophosphate (cGMP) level of CMP-treated rats was normal but addition of GTN increased cGMP and NO concentration more in CMP-treated rats than in controls, an effect unaltered by addition of diadzin. Taken together, CMP appears partially responsible for the improvement in cardiovascular health markers caused by coconut milk in middle-aged male rats

Effect of consumption of whole egg and egg fractions on cardiovascular disease factors in adult rats.

BACKGROUND: While eggs are a low-cost source of protein, rich in macro- and micronutrients, the association of egg intake and cardiovascular disease (CVD) remains controversial. This study investigated the effect of egg consumption on CVD parameters. Eggs were boiled, separated into four fractions (whole egg, 50% yolk-reduced whole egg, egg yolk and egg white) and then freeze-dried. The different egg fractions or distilled water (control) were orally gavaged to adult male Wistar rats at 1 g kg-1 rat body weight, each day for 8 weeks, following which basal blood pressure, heart rate, complete blood cell count, blood biochemistry, body fat and liver cell lipid accumulation were determined. The vascular functions of isolated thoracic aorta were studied using classical pharmacological techniques. RESULTS: In comparison to the control group, none of the egg fractions affected body weight, food intake, plasma glucose or lipid profile. The yolk group experienced increased plasma alkaline phosphatase and creatinine levels, while egg white caused decreased plasma cholesterol and blood urea nitrogen. Whole egg and egg yolk increased blood pressure and mean hemoglobin concentration and the yolk increased liver lipid accumulation. Egg white decreased the white blood cell count and body fat lipids. No changes were found in basal heart rate or vascular functions in any of the groups. CONCLUSIONS: Consumption of whole egg or egg yolk at the dosage given caused hypertension, with impairment of liver and kidney functions following the intake of yolk alone. However, egg white is beneficial for the cardiovascular system as it decreased plasma cholesterol and body fat accumulation. © 2020 Society of Chemical Industry.

6 weeks consumption of pure fresh coconut milk caused up-regulation of eNOS and CSE protein expression in middle-aged male rats

Coconut milk (CCM) has been an important cooking ingredient in the Asia-Pacific region since ancient time. Due to its high content of saturated fatty acids, it has been considered atherogenic. We have tested if chronic consumption of fresh coconut milk by middle-aged male rat affects vascular function, plasma glucose and lipid profiles. Compared to control, CCM caused lower maximal contraction to phenylephrine of thoracic aortic rings and increased relaxation to acetylcholine that was abolished by N G-nitro-L-arginine (L-NA) or disruption of the endothelium. DL-propargylglycine caused slight increase in baseline tension of L-NA treated aortic rings of CCM-treated rats and produced higher contractile response of the aortic rings to low concentrations of phenylephrine. The aortic eNOS- and cystathionine-γ-lyase(CSE) proteins expression of the CCM-treated rats were also higher than in controls. Except for lower fasting plasma glucose there were no changes in blood chemistry for the CCM treated rats. CCM consumption caused up-regulation of eNOS and CSE protein expression which resulted in increased production of NO and H2S from the blood vessels with attenuation of vasocontraction to phenylephrine and increased relaxation to acetylcholine. These novel benefits may be expected to reduce the development of cardiovascular risk factors in the aging rat
