Working from the foundation of the role of diet in the pathogenesis of hyperlipidemia, the authors present a rational, detailed therapy for treating the disorder. A three-phase approach is offered so that the patient can gradually incorporate new eating behavior into his or her lifestyle.

This research investigated the antihypertensive effects of tamarind products and compared their potentials based on an animal model's data verified by molecular docking, multitarget interactions, and dynamic simulation assays. GC-MS-characterized tamarind products were administered to cholesterol-induced hypertensive albino rat models. The two-week-intervened animals were dissected to collect their serum and organs and respectively subjected to analyses of their hypertension-linked markers and tissue architectures. The lead biometabolites of tamarinds interacted with eight target receptors in the molecular docking and dynamic simulation studies and with multitarget in the network pharmacological analyses. The results show that the serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), C-reactive protein (CRP), troponin I, and lipid profiles were maximally reinstated by the phenolic-enriched ripened sour tamarind extract compared to the sweet one, but the seed extracts had a smaller influence. Among the tamarind's biometabolites, ϒ-sitosterol was found to be the best ligand to interact with the guanylate cyclase receptor, displaying the best drug-likeliness with the highest binding energy, -9.3 Kcal. A multitargeted interaction-based degree algorithm and a phylogenetic tree of pathways showed that the

The lymphatic recovery of radiolabeled sitosterol administered in various amounts to the stomach was almost the same between stroke-prone spontaneously hypertensive rats (SHRSPs), a strain having a missense mutation in ATP binding cassette transporter g5 (Abcg5), and Wistar rats, a normal strain. The results suggest that the mutation of Abcg5 in SHRSPs, compared with Wistar rats, did not influence the ability for intestinal sitosterol absorption regardless of the dose.

In recent studies, the life span of stroke-prone spontaneously hypertensive (SHRSP) rats was altered by a variety of dietary fats. It was relatively shorter in rats fed canola oil as the sole source of fat. The present study was performed to find out whether the fatty acid profile and the high content of sulfur compounds in canola oil could modulate the life span of SHRSP rats. SHRSP rats (47 d old, n = 23/group) were matched by body weight and systolic blood pressure and fed semipurified diets containing 10% canola oil, high-palmitic canola oil, low-sulfur canola oil, soybean oil, high-oleic safflower oil, a fat blend that mimicked the fatty acid composition of canola oil, or a fat blend high in saturated fatty acids. A 1% sodium chloride solution was used as drinking water to induce hypertension. After consuming the diets for 37 d, five rats from each dietary group were killed for collection of blood and tissue samples for biochemical analysis. The 18 remaining animals from each group were used for determining their life span. The mean survival time of SHRSP rats fed canola oil (87.4+/-4.0 d) was not significantly different (P > 0.05) from those fed low-sulfur canola oil (89.7+/-8.5 d), suggesting that content of sulfur in canola oil has no effect on the life span of SHRSP rats. The SHRSP rats fed the noncanola oil-based diets lived longer (mean survival time difference was 6-13 d, P < 0.05) than those fed canola and low-sulfur canola oils. No marked differences in the survival times were observed among the noncanola oil-based groups. The fatty acid composition of the dietary oils and of red blood cells and liver of SHRSP rats killed after 37 d of treatment showed no relationship with the survival times. These results suggest that the fatty acid profile of vegetable oils plays no important role on the life span of SHRSP rat. However, phytosterols in the dietary oils and in liver and brain were inversely correlated with the mean survival times,indicating that the differential effects of vegetable oils might be ascribed, at least partly, to their different phytosterol contents.

At hospital admission drugs prescribed by the general practitioner (GP) are often changed. This may have a negative impact on the relationship between family and hospital physicians as well as on the family doctor-patient-relationship. The study set out to examine the attitudes of hospital physicians towards GPs' prior ambulatory medication, especially in the case of drugs of unproven efficacy (e.g. certain drug combinations and homeopathic or herbal drugs).. A total of 129 doctors of the surgical and medical wards of the Göttingen University Hospital received a standardized questionnaire focusing on drugs prescribed by referring GPs (response rate: 65.9%). Three case vignettes were presented describing "popular" GP prescriptions. Doctors of surgical and medical departments were asked whether or not they would follow these prescriptions. Differences in the answers between the groups of doctors were tested by Fisher's exact test.. More doctors on the surgical than on the medical wards would usually follow GPs' medication (82 vs 25%; P < 0.001). According to these attitudes, more doctors of medical departments would stop the prescription of drug combination (82 vs 41%; P < 0.001); both groups would be hesitant to accept homeopathic drugs (89 vs 59%; P < 0.01) or herbal drugs (89 vs 55%; P < 0.01) as prescribed by the GP. The critical attitude especially of doctors of the medical departments towards drug combinations and herbal drugs was in line with their decision in the case vignettes (e.g. Capozide, Tebonin forte).. Especially doctors working in medical departments keep in line with conventional clinical pharmacological criteria. If they have to decide whether or not to follow patients' ambulatory medication, they may overlook GPs' decision-making process underlying their prescribing.
