Cannabis sativa and/or melatonin do not alter brain lipid but alter oxidative mechanisms in female rats

Abstract Background Lipid profile and redox status play a role in brain (dys)functions. Cannabinoid and melatonergic systems operate in the brain and contribute to brain (patho)physiology, but their roles in the modulation of brain lipid and redox status are not well-known. We studied the effect of ethanol extract of Cannabis sativa (CS) and/or melatonin (M) on the lipid profile and anti-oxidant system of the rat brain. Methods We randomly divided twenty-four (24) female Wistar rats into 4 groups (n = 6 rats each). Group 1 (control) received distilled water mixed with DMSO. Groups II–IV received CS (2 mg/kg), M (4 mg/kg), and co-administration of CS and M (CS + M) respectively via oral gavage between 8:00 am and 10:00 am once daily for 14 days. Animals underwent 12-h fasting after the last day of treatment and sacrificed under ketamine anesthesia (20 mg/kg; i.m). The brain tissues were excised and homogenized for assay of the concentrations of the total cholesterol (TC), triacylglycerol (TG), high-density lipoprotein cholesterol (HDL-C), nitric oxide (NO), malondialdehyde (MDA), and the activities of glucose-6-phosphate dehydrogenase (G6PD), glutathione reductase (GR), glutathione peroxidase (GPx), catalase (CAT), superoxide dismutase (SOD), and acetylcholinesterase (AChE). One-way analysis of variance (ANOVA) was used to compare means across groups, followed by the least significant difference (LSD) post-hoc test. Results CS and/or M did not affect the lipid profile parameters. However, CS increased the G6PD (from 15.58 ± 1.09 to 21.02 ± 1.45 U/L; p = 0.047), GPx (from 10.47 ± 0.86 to 17.71 ± 1.04 U/L; p = 0.019), and SOD (from 0.81 ± 0.02 to 0.90 ± 0.01 μM; p = 0.007), but decreased NO (from 9.40 ± 0.51 to 6.75 ± 0.21 μM; p = 0.010) and had no effect on MDA (p = 0.905), CAT (p = 0.831), GR (p = 0.639), and AChE (p = 0.571) in comparison with the control group. M augmented the increase in G6PD (from 21.02 ± 1.45 U/L to 27.18 ± 1.81 U/L; p = 0.032) and decrease in NO (from 6.75 ± 0.21 to 4.86 ± 0.13 μM; p = 0.034) but abolished the increase in GPx (from 17.71 ± 1.04 to 8.59 ± 2.06 U/L; p = 0.006) and SOD (from 0.90 ± 0.01 to 0.70 ± 0.00 μM; p = 0.000) elicited by CS in the rat brain in comparison with the CS group. Conclusions CS and M do not alter brain lipid profile. Our data support the contention that CS elicits an anti-oxidative effect on the brain tissue and that CS + M elicits a pro-oxidant effect in rat brain.

Lipids are essentials components of the brain. Changes in brain lipid composition affect the physical and functional properties of the neuronal cell membrane and have been implicated in the physiopathology of Alzheimer disease (AD). We evaluated in this study the effect of hydroethanolicbark extract of A. Congolensis on lipid profile of rats’ brain with experimentally induced AD. The experimental model consisted of female rats, which received orally for 8 consecutive weeks a single dose of 50 mg/Kg b.w./day of aluminum trichloride (AlCl3) (except control group) followed by distilled water (disease control group) or doses of the extract (150 or 300 mg/Kg b.w./day) or vitamin E (100 mg/Kg b.w./day) or galanthamine (2 mg/Kg b.w. /day). Brain cholesterol, phospholipids and plasmalogenlevels and fluidity were evaluated. Brain membranes ATPase activities, Ca2+, Mg2+and glucose levels were also assayed. Significant modifications of brain lipid composition and fluidity were observed in disease control group compared with control. In addition, Na+, K+-ATPase and Mg2+-ATPase activities significantly decreased, the level of intracellular Ca2+ increased, Mg2+ content decreased and brain glucose level was significantly higher. Standard drugs (vitamin E,galanthamine) showed a negative effect on brain lipid profile. The extract of 150 mg showed significant improvements of brain lipid profile and fluidity. It also indicated improved brain ATPase activities, ions and glucose brain homeostasis. The extract (150 mg/Kg b.w. dose) by maintaining the brain lipid composition may protect neuronal cell membraneand probably preventing the progression of AD.

Aims: By using histological analysis, the study aims to evaluate the effect of a nutraceutical based on the Amazonian fruits of camu-camu (Myrciaria dubia (Kunth) Mc Vaugh), acai (Euterpe precatoria Mart.) and guarana (Paullinia cupana) on the brain tissue (hippocampus) of dyslipidemic rats. Methodology: Preclinical trials were conducted using male and female rats (n=30) of the Wistar strain (Rattus norvegicus) that were randomly divided into five groups (G) (n=6). G1 was control, G2 was induced to obesity with consumption of experimental feed (hypercaloric and hyperlipidic), G3 was induced to obesity with consumption of experimental feed and treated with simvastatin (50 mg/kg/day), and G4 and G5, which were induced to obesity with the consumption of experimental feed and supplemented with 100 mg/kg/day and 200 mg/kg/day of the formulation, respectively. The study period was 72 days, and, for 37 days, induction to obesity was performed with the experimental feed (hypercaloric and hyperlipidic). During the following weeks, for 35 days, after division of the groups, certain groups received, in parallel, treatment with simvastatin (G3) or supplementation with the nutraceutical (G4 and G5). Subsequently, histological slides of the brain tissue stained with violet cresyl were elaborated, photographed and analyzed. Results: No significant differences were observed between the mean of intact neurons among the experimental groups induced to obesity. The neurotoxic effect, evidenced by the significant difference between the mean of intact neurons between the control group and obesity-induced groups, corroborates the findings of neuronal damage and degenerative processes reported in the literature. Conclusion: The nutraceutical based on Amazonian fruits was not able to prevent the neurotoxic effect arising from the hyperlipidic and hypercaloric diet, and therefore did not present a neuroprotective effect in Wistar rats under the conditions established in the experiment.

Abstract Background Dyslipidemia has been reported in patients with virus infections. This study was performed to evaluate the blood lipid profile in the patients with coronavirus disease 2019 (COVID-19), and exploring the underlying factors in its development and their predictive value for the severity of COVID-19.Methods In a case-control study, the lipid profile of patients with COVID-19 at the first admitted to two clinical centers in the west of Iran (July 2020 to Dec. 2020) and age- and gender-matched healthy people were explored. Three groups of controls, patients with the severe form of Covid-19 (admitted to the intensive care unit (ICU)), patients with Covid-19 with less intensity (outpatient admission), were defined for the subjects included in the study. The predictive values of different variables obtained from medical records for COVID-19 severity were analyzed.Results Generally, 48 outpatients and 49 ICU patients, including 70 men and 23 women with a mean age of 62.4±13.5 years, were included in the study. The control group consisted of 32 people, match sex and age with the patient groups. The mean triglyceride (TG) in the Covid-19 groups was higher than the control group, but there was no significant difference between them. The mean cholesterol in the patient groups was lower than the control group (p=0.001). The mean of low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) was significantly different in the patient groups; HDL-C in the ICU group was more than outpatient, and LDL-C in the outpatient group was more than ICU (P<0.05). LDL-C and HDL-C in the ICU group were less than the control group, but there was no statistically significant difference between the two mentioned groups. The frequency of diabetes and hypertension was higher in the ICU group than in the outpatient group (P<0.001). Furthermore, LDL-C level was associated with disease severity (odds ratio (OR): 0.966, 95% confidence interval (CI): 0.944-0.989, P= 0.004).Conclusion Lipid profiles in Covid-19 patients have different faces from healthy individuals. In the severe form, the lipid status has a different profile from the less severe form of Covid-19 disease. LDL-C level can be used as an indicator to determine the severity of Covid-19 disease.

Methadone Maintenance Therapy (MMT) has been accepted as a gold-standard treatment for opioid therapy. It may associate with adverse effects. This study aimed to affect methadone on serum lipid profile, leptin levels, and liver enzymes in male and female rats. 41 Wistar rats weighing 200-300gr were randomly assigned into four groups, including two methadone treatments and two control groups, both male and female, that received 5mg/kg methadone or 1cc normal saline daily for 8 weeks respectively by gavage method. All animals were weighed weekly. Fasting blood sugar (FBS) was measured by a glucometer, and blood samples were taken by cardiac puncture for triglyceride, low-density lipoprotein (LDL),high-density lipoprotein (HDL), total cholesterol, Aspartate transaminase (AST), Alanine transaminase (ALT), alkaline phosphatase (ALP) and leptin levels measurement after 12h fasting. One-way ANOVA showed no significant difference in mean FBS, total cholesterol, triglyceride, and LDL levels among the four groups. Moreover, there was a statistically significant difference in the mean of HDL, ALT, AST, and ALP levels. Furthermore, repeated measures ANOVA indicated a significant increase in body weight of rats during 8 weeks. Our findings indicated changes in some metabolic effects associated with methadone treatment in a gender-dependent manner.

Background: Lichen planus (LP) is a chronic inflammatory disease, involving the skin, mucous membranes, hair, and nails. Cardiovascular risk factors have been assessed with some chronic inflammatory skin diseases such as alopecia and psoriasis. Recently, some studies found that lichen planus (LP) was associated with dyslipidemia. So we did this study to find this association in our patients. Objective: To evaluate lipid levels in patients with L.P and compare it with controls. Materials and Methods: This case- control study included 160 participators (80 with L.P. and 80 controls) admitted to dermatology clinic at Tishreen University Hospital, Lattakia, Syria, from 2020- 2021. Results: Cholesterol, triglyceride and Low- density lipoprotein (LDL) levels in patients were significantly higher than the control group; it was only regarding high- density lipoprotein (HDL) levels that no significant difference was observed between the two groups. Triglyceride levels were significantly higher and HDL levels were lower in patients with diffused disease. There was a recognizable correlation between elevated levels of LDL and cholesterol with disease duration. Conclusion: In this study, a disrupted lipid profile was observed in LP patients, which can be associated with disease severity. This study proposes measuring lipid serum levels prior to commencing the treatment in all known cases of lichen planus, so as to preclude cardiovascular diseases if there is a problem with the lipid profile.

Artichoke Leaf Extract

Introduction: Hyperlipidemia is considered a prominent risk factor for coronary heart disease. Coronary heart disease is the most common cause of mortality and morbidity in chronic kidney disease (CKD) patients. Objectives: The aim of this study was to evaluate the effects of artichoke leaf extract (ALE) supplementation on the lipid profile of CKD patients. Patients and Methods: A randomized, double-blind, placebo-controlled clinical trial was conducted in 38 CKD subjects (GFR<60 and >15 mL/min/1.73 m2 ) with hypercholesterolemia (total cholesterol ≥ 200 mg/dL or low-density lipoprotein cholesterol [LDL-C] ≥ 110 mg/dL). The intervention group received an artichoke capsule (320 mg) and an indistinguishable placebo was given to the control group twice daily for 6 weeks. Lipid profile and appetite were assessed at week 8 and the results were compared with the baseline data. Results: ALE supplementation was correlated with a statistically significant decrease in mean total cholesterol (P=0.028) and LDL-C (P=0.005) compared to the control group. The two groups did not show a significant difference in high-density lipoprotein-cholesterol (P=0.071) and triglyceride levels (P=0.22). There was a statistically significant difference in appetite between the two groups (P=0.016). Conclusion: This randomized controlled trial demonstrated that consumption of ALE supplement may improve appetite and lipid profile in CKD patients.
