A study was conducted to evaluate the effect of traditional Chinese herbal medicines (TCHM) on egg production, egg quality and antioxidant enzyme activities in chickens, astragalus membranaceus (AM), angelicae sinensis extract (ASE) and danggui buxue san (DBS) were used for the study. 300 hens of 56 weeks of age were randomized into 10 groups. AM, ASE and DBS were added into the diets of the animals at the dosage of 5mg/Kg,10 mg/Kg and 15 mg/Kg respectively from group Ito group IX. The hens of group X, as of control, were fed with the diet without TCHM. The added TCHM Period was 15 days. The results showed that DBS had the ability on improving egg production, egg quality and antioxidant enzyme activities in chickens. At the same time, DBS was added into the diets of the animals at the dosage of 10mg/Kg was recommended for application.

BACKGROUND Recent studies revealed that most discharged patients with COVID-19 suffered ongoing symptoms months later. Rehabilitation interventions can help address the consequences of COVID-19. These include medically, physically, cognitively and psychologically related problems. To our knowledge, no studies have investigated the effects of rehabilitation following discharge from hospital. OBJECTIVE The specific aims of this project are to investigate the effects of a 12-week exercise program on pulmonary fibrosis in recovering COVID-19 patients. A further aim will be to examine how Chinese herbal medicines, gut microbiome and its metabolites regulate immune function and possibly autoimmune deficiency in the rehabilitation process. METHODS In this triple-blinded, randomized, parallel groups, controlled clinical trial, we will recruit adult patients with COVID-19 who have been discharged from the hospital in Hong Kong and are suffering from impaired lung function and pulmonary function. A total of 172 eligible patients will be randomized into four equal groups: 1) cardiorespiratory exercise plus Chinese herbal medicines group, 2) cardiorespiratory exercise only group, 3) Chinese herbal medicines only group and 4) waiting list group (in which participants will receive Chinese herbal medicines after 24 weeks). These treatments will be administered for 12 weeks with a 12-week follow-up period. Primary outcomes include dyspnea, fatigue, lung function, pulmonary function, blood oxygen levels, immune function, blood coagulation, and related blood biochemistry. Measurements will be recorded prior to initiating the above treatments and repeated at the 13th and 25th weeks of the study. The primary analysis is aimed at comparing the outcomes between groups throughout the study period with alpha level of 0.05 (two-tailed). RESULTS The trial has not been recruiting patients. The proposed study will be completed in 24 months from 01 Jan 2021 to 31 Dec 2022. CONCLUSIONS NA CLINICALTRIAL ClinicalTrials.gov NCT04572360; https://clinicaltrials.gov/ct2/show/NCT04572360

Background: Lipid is considered as one of the essential nutrients for both humans and animals. Lipid accumulation within the body may induce several health disorders. Disease is are caused easily in aged laying hens. It is necessary to improve lipid metabolism and enhance immunity in laying hens. Traditional Chinese veterinary medicine (TCVM) with no toxicity and low drug residues is becoming more and more popular. The current study aimed to study the effect of Chinese herbal medicines on lipid metabolism and immunity function in chicken to provide basis for clinical reference. Methods: In this laboratory investigation during 2018-2019, a total of 400 60-week-old hens were randomized into 10 groups to measure lipid metabolism by colorimetry and immunoglobulin by double antibody sandwich ELISA method. A total of 500 28-day-age chickens were randomized into 10 groups to measure immune organ index. The experiment lasted for 42 days. Result: Our investigations have showed that Jujube (ZJM) has significant effects on the count of Serum total cholesterol (TC), Triglyceride (TG), Low-density lipoprotein-c (LDL-C) and High-density lipoprotein-c (HDL-C) (p less tha 0.01, p less than 0.05),the count of Immunoglobulin-G (IgG) (p less than 0.05) and the immune organ indexes (p less than 0.05) in 30 mg/kg group than control group10.The present work will be a complementary contribution to the ability of ZJM on improving lipid metabolism and immunity function in chickens.
