Subacute Oral Administration of Clinacanthus nutans Ethanolic Leaf Extract Induced Liver and Kidney Toxicities in ICR Mice. Molecules 2020; 25:molecules25112631. [PMID: 32517000 PMCID: PMC7325574 DOI: 10.3390/molecules25112631] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2020] [Revised: 04/27/2020] [Accepted: 04/27/2020] [Indexed: 11/16/2022] Open
Abstract
This study investigated the leaves of Clinacanthus nutans for its bioactive compounds and acute and subacute toxicity effects of C. nutans ethanolic leaf extract (CELE) on blood, liver and kidneys of ICR mice. A total of 10 8-week-old female mice were divided into groups A (control) and B (2000 mg/kg) for the acute toxicity study. A single dose of 2000 mg/kg was administered to group B through oral gavage and mice were monitored for 14 days. In the subacute toxicity study, mice were divided into five groups: A (control), B (125 mg/kg), C (250 mg/kg), D (500 mg/kg) and E (1000 mg/kg). The extract was administered daily for 28 days via oral gavage. The mice were sacrificed, and samples were collected for analyses. Myricetin, orientin, isoorientin, vitexin, isovitexin, isookanin, apigenin and ferulic acid were identified in the extract. Twenty-eight days of continuous oral administration revealed significant increases (p < 0.05) in creatinine, ALT and moderate hepatic and renal necrosis in groups D and E. The study concluded that the lethal dose (LD50) of CELE in mice is greater than 2000 mg/kg and that repeated oral administrations of CELE for 28 days induced hepatic and renal toxicities at 1000 mg/kg in female ICR mice.

Hair ethyl glucuronide levels as a marker for alcohol use and abuse: a review of the current state of the art. Drug Alcohol Depend 2014; 134:1-11. [PMID: 24239414 DOI: 10.1016/j.drugalcdep.2013.10.008] [Citation(s) in RCA: 98] [Impact Index Per Article: 9.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/27/2013] [Revised: 10/07/2013] [Accepted: 10/13/2013] [Indexed: 12/16/2022]
Abstract
BACKGROUND Ethyl glucuronide (EtG) is a minor alcohol metabolite that has been proposed as a stable marker in hair to detect and quantify alcohol consumption over long time periods. METHODS We provide an outline of currently available techniques for EtG hair sample analysis and highlight the pitfalls related to data interpretation. The literature of EtG analysis has been reviewed from January 1980 up to August 2013. In addition, we present an overview of the clinical and forensic studies which have used EtG quantification in hair as a marker for alcohol consumption/abstinence and we provide suggestions for future research. RESULTS EtG is a stable marker in hair that can be used to detect and quantify alcohol consumption over long time periods. This alcohol metabolite remains in hair after complete elimination of alcohol. Currently, there are three main analytical techniques used to quantify EtG in hair: gas chromatography-mass spectrometry (GC-MS), gas chromatography-tandem mass spectrometry (GC-MS/MS), and liquid chromatography-tandem mass spectrometry (LC-MS/MS). No standardized protocols are yet available for the analysis of EtG levels in hair samples, and the current protocols vary in sample preparation and extraction procedures. Variables such as hair length, cosmetic treatment, gender, and pathophysiological conditions influence the final results and should be taken into account. CONCLUSIONS EtG quantification in hair is a useful tool for the objective detection of alcohol consumption over extended time periods, but care should be taken when interpreting the results.

Abstract
BACKGROUND All living organisms are made of individual and identifiable cells, whose number, together with their size and type, ultimately defines the structure and functions of an organism. While the total cell number of lower organisms is often known, it has not yet been defined in higher organisms. In particular, the reported total cell number of a human being ranges between 10(12) and 10(16) and it is widely mentioned without a proper reference. AIM To study and discuss the theoretical issue of the total number of cells that compose the standard human adult organism. SUBJECTS AND METHODS A systematic calculation of the total cell number of the whole human body and of the single organs was carried out using bibliographical and/or mathematical approaches. RESULTS A current estimation of human total cell number calculated for a variety of organs and cell types is presented. These partial data correspond to a total number of 3.72 × 10(13). CONCLUSIONS Knowing the total cell number of the human body as well as of individual organs is important from a cultural, biological, medical and comparative modelling point of view. The presented cell count could be a starting point for a common effort to complete the total calculation.

Abstract
This study was conducted to determine the effect of feeding three differently processed mixtures on health status of broilers. A total of 1080 day-old Marshal broilers were fed; discarded vegetable-fresh bovine blood-fresh rumen digesta (P1), discarded vegetable-ensiled bovine blood-fresh rumen digesta (P2) and discarded vegetable-fresh bovine blood-ensiled rumen digesta (P3) at three levels of inclusion (0, 3 and 6%). Data on blood parameters was taken and were subjected to 3 x 3 factorial arrangements in a completely randomized design. Birds fed P1 had least values (p < 0.05) of serum glucose, total protein, globulin, uric acid and creatinine at starter phase. Birds fed diets containing 3 and 6% level of inclusion recorded the highest (p < 0.05) Packed cell volume, Haemoglobin, White blood cell and Red blood cell values. However, those fed at 0% level of inclusion recorded the highest albumin value. At finisher phase, birds fed P2 and P3 had the highest glucose, uric acid and creatinine values. 6% level of inclusion significantly (p < 0.05) increased the total protein and albumin values. Therefore, for enhanced performance and without comprising the health condition of birds; broiler chickens could be fed diets containing discarded vegetable-fresh bovine blood-ensiled rumen digesta (P3) up to 6% level of inclusion.

Abstract
BACKGROUND Alcohol abuse is associated with several gastrointestinal diseases, such as esophageal carcinoma, chronic alcoholic pancreatitis, and liver cirrhosis. Increased mean corpuscular volume (MCV) has been recognized as a biomarker for alcohol abuse and heavy drinkers. Recent studies from Japan revealed that macrocytosis is related to ALDH-2/2 genotype, leading to increased acetaldehyde accumulation. It has also demonstrated that increased MCV values could also be an independent biomarker for esophageal cancer in Asians. Therefore, the aim of the current study was to investigate possible associations of MCV value with polymorphisms of ADH1C in white patients with alcohol-associated esophageal carcinoma, chronic alcoholic pancreatitis, and alcoholic cirrhosis as well as in heavy drinkers without organ damage. METHODS In this study, a total of 510 alcoholic patients were enrolled with esophageal cancer (n = 98), chronic pancreatitis (n = 98), alcoholic liver cirrhosis (n = 151), and alcohol abuse without gastrointestinal disease (n = 163). ADH1C genotyping was performed by PCR-based restriction fragment length polymorphism (PCR-RFLP) analysis from whole blood. The relation between MCV and ADH1C gene polymorphisms (ADH1C*1 and 1C*2) controlled for the amount of drinking, smoking, and age were investigated using both univariate and multivariate analysis. RESULTS In univariate analysis, higher alcohol consumption was associated with increased MCV. Other variables were not associated with macrocytosis. In multiple linear regression analysis, after adjustment for age and smoking, higher alcohol consumption and female sex were independently associated with higher MCV values. No other variables, including which alcohol-associated disease the patient had, had an independent effect. Adding ADH genotype rendered no independent significant effect on MCV value. CONCLUSIONS In a white population, MCV values were not associated with genotype polymorphisms of ADH1C. In contrast to findings in Asians, macrocytosis does not seem to be an independent biomarker for esophageal cancer. The role of ADH1C polymorphism in increasing MCV and the potential use of MCV as a marker for esophageal carcinoma are still pending.
