Astragaloside IV has so many benefits

Astragaloside IV, the main component of the traditional Chinese medicine astragalus membra-naceus, has been shown to inhibit inflammation, oxidation, and apoptosis, and exerts immu-noregulatory effects. 

Astragaloside IV is one of the main active compounds of Astragalus membranaceus Bunge. Experimental studies from several laboratories,have provided abundant evidence demonstrating the explicit cardiovascular-protective effects of Astragaloside IV(CAS NO:84687-43-4). 

Now, let’s talk about what can we benefit from Astragaloside IV in detail.

1.Immunostimulant: acting through a number of different pathways, especially,by increasing the number of stem cells in the spinal cord and lymphatic tissue and encouraging them to develop into active immune cells or stimulating production of immunoglobulins and macrophages.

2.Neuroprotective: in traditional Chinese medicine, astragalus root extract is used to treat neurodegenerative diseases. One study demonstrated the capacity of astragaloside IV(CAS NO:84687-43-4) to protect dopaminergic neurons (progressive degeneration of dopaminergic neurons leads to the development of Parkinson's disease). 

3.Antibacterial: as demonstrated by in vitro studies on Shigella dysenteriae, Streptococcus haemolyticus, Diplococcus pneumoniae and Staphylococcus aureus. 

4.Antiviral: inhibiting replication of certain viruses such as coxsackie, responsible for myocarditis (inflammation of the heart muscle). In both animal and human studies, they were shown to stimulate endogenous interferon production and to maximise its effect on viral infections. 

5.Anti-inflammatory: as shown in certain animal models. The ability of astragaloside IV to stem inflammation of the airways in chronic asthma has been reported in studies on mice. 

6.Inhibitory: against formation of the AGEs involved in neuropathic complications of diabetes.

7.Protective: against the toxic effects of chemotherapy. Astragalus extract boosts resistance to the immunosuppressive effects of chemotherapy drugs by encouraging macrophages to product interleukin 6 and tumour necrosis factor. 

8.Antioxidant: inhibiting lipid peroxidation by 40% in vitro. These antioxidant properties may go some way to explaining the cardio- and neuro-protective effects of astragalus and astragaloside IV. 

9.Cardioprotective: with studies highlighting health benefits for patients with congestive cardiac insufficiency and angina pectoris. Astragalus extracts have a cardiotonic effect. 

With so many beneficial properties, particularly immunostimulant, anti-inflammatory, antioxidant and anti-glycation, Astragaloside IV is a truly essential anti-aging supplement. Its exceptional properties are due to Astragaloside IV specific ability to activate telomerase, thus slowing down the shortening of telomeres, and extending cell lifespan. Shortening of telomers is associated with cellular ageing and the development of age-related diseases.

A report on Chromic acid

A man who fell into a barrel of Chromic acid while at work Monday followed correct procedures and is recovering in a Grand Rapids, Mich., hospital, his employer said.

The man, 45, is a 10-year employee of Lacks Enterprises in Grand Rapids and was performing a maintenance function when he slipped and fell into a tank of diluted chromic acid(CAS: 7738-94-5), a toxic and carcinogenic element of the chrome-plating process, the news website MLive.com reported Monday.

It added only the man's legs were dunked in the acid.Jim Green, human resources director of the firm, said the employee was wearing a safety harness and other appropriate equipment when the accident occurred, and fellow employees hosed the victim down according to protocol.

"I spoke to him personally today, and hope to be in touch with him again soon. We anticipate a full recovery," Green said of the employee's injuries.

Chromic acid(CAS:7738-94-5)was widely used in the instrument repair industry, due to its ability to "brighten" raw brass. A chromic acid dip leaves behind a bright yellow patina on the brass. Due to growing health and environmental concerns, many have discontinued use of this chemical in their repair shops.

In this article, we can talk something about the Potential Health Effects of chromic acid.

Inhalation: Corrosive. Extremely destructive to tissues of the mucous membranes and upper respiratory tract. May cause ulceration and perforation of the nasal septum. Symptoms may include sore throat, coughing, shortness of breath, and labored breathing. May produce pulmonary sensitization or allergic asthma. Higher exposures may cause pulmonary edema. 

Ingestion: Corrosive. Swallowing can cause severe burns of the mouth, throat, and stomach, leading to death. Can cause sore throat, vomiting, diarrhea. May cause violent gastroenteritis, peripheral vascular collapse, dizziness, intense thirst, muscle cramps, shock, coma, abnormal bleeding, fever, liver damage and acute renal failure. 

Skin Contact: Corrosive. Symptoms of redness, pain, and severe burn can occur. Dusts and strong solutions may cause severe irritation. Contact with broken skin may cause ulcers (chrome sores) and absorption, which may cause systemic poisoning, affecting kidney and liver functions. May cause skin sensitization. 

Eye Contact: Corrosive. Contact can cause blurred vision, redness, pain and severe tissue burns. May cause corneal injury or blindness. 

Chromic acid Exposure: Repeated or prolonged exposure can cause ulceration and perforation of the nasal septum, respiratory irritation, liver and kidney damage and ulceration of the skin. Ulcerations at first may be painless, but may penetrate to the bone producing "chrome holes." Known to be a human carcinogen. 

Aggravation of Pre-existing Conditions: Persons with pre-existing skin disorders, asthma, allergies or known sensitization to chromic acid or chromates may be more susceptible to the effects of this material.

New study on Diethylamine

Diethylamine is a secondary amine with the molecular structure CH3CH2NHCH2CH3 (also written as C4H11N). It is a flammable, strongly alkaline liquid. It is miscible with water and ethanol. It is a colorless liquid which often appears brown due to impurities. It is volatile and has a strong unpleasant odor, the Molecular Weight is 73.14, and CAS Registry Number is 109-89-7.

Topical diclofenac Diethylamine 1.16% gel is an NSAID that is clinically proven to be effective and well tolerated in acute and chronic musculoskeletal conditions. Applied topically, diclofenac penetrates the skin barrier to reach joints, muscles and synovial fluid. It preferentially distributes and persists in the target inflamed tissues, achieving a sufficiently high concentration to exert local therapeutic activity. 

Therefore, this randomized, double-blind, placebo-controlled study aimed to assess its efficacy and safety in the treatment of acute NP. The primary objective of the study was to assess the efficacy of Diethylamine(CAS NO:109-89-7) 1.16% gel compared with placebo gel in the treatment of acute NP in terms of pain-on-movement at 48 h (Day 3) from baseline. Secondary objectives included the effect of Diethylamine 1.16% gel on pain-at-rest (PAR), functional impairment (using the neck disability index, NDI), patients’ global assessment of treatment efficacy and safety following application for 5 days.

The clinical study was designed, implemented and reported in accordance with the International Conference on Harmonization Harmonized Tripartite Guidelines for Good Clinical Practice and with the ethical principles laid down in the Declaration of Helsinki. The study protocol, protocol amendment and associated documents were reviewed by an Independent Ethics Committee in Germany. Informed consent was obtained from each subject in writing before randomization and the rights of subjects were protected.

The primary efficacy variable was POM after 48 h. Secondary efficacy variables included POM at all other visits, PAR and NDI score at Days 2, 3 and 5, response to treatment, early response to treatment, global assessment of treatment efficacy at Days 3 and 5 and use of rescue medication.

In total, 72 subjects were randomized to treatment between April 2011 and July 2011; 36 to Diethylamine 1.16% gel and 36 to placebo gel. All 72 patients completed the study and were included in the ITT population. The mean age was 33.8 years, with an almost equal number of males and females, and all subjects were Caucasian. 

Overall, subjects had neck pain at baseline for about 10 days, an NDI score (24.5) midway the best and worst outcomes (0, 50), mild-to-moderate PAR (40.6 mm) and severe POM (75.5 mm). The treatment groups did not differ appreciably on any demographic or baseline neck pain characteristics. In particular, POM in the Diethylamine 1.16% gel and placebo groups were comparable at baseline (77.2 mm vs. 73.8 mm, respectively).

The recent development in the field of ranolazine

Molecular Formula:C24H33N3O4
Molecular Weight: 427.54
Density:1.174 g/cm3
Boiling Point:624.1 C at 760 mmHg
Flash Point:331.2 C
Appearance: white solid
CAS Registry Number:95635-55-5
Usage: Anti-ischemic agent which modulates myocardial metabolism.

Ranolazine is used alone or with other medications to treat ongoing angina (chest pain or pressure that is felt when the heart does not get enough oxygen). Ranolazine is in a class of medications called anti-anginals. The exact way that ranolazine works is not known at this time.

Ranolazine(CAS NO: 95635-55-5) is a medication that belongs to the drug class known as cardiovascular agents. Ranexa is prescribed for the treatment of chronic angina. Common side effects of Ranexa include dizziness, nausea, constipation, headache, swelling in hands, ankles, or feet, slow, fast, or irregular heartbeats, tremors, blood in the urine and shortness of breath.

This is the recent development in the field of ranolazine. This study was done in 6560 post-ACS NSTEMI patients followed up for one year. Although ranolazine did not show significant benefit in the study's primary endpoints of cardiovascular death, myocardial infarction, or recurrent ischemia; it exhibited a potential benefit in arrhythmia.

Earlier, ranolazine increasing QT interval (about 2 to 6 ms) was of concern, which has a theoretical risk of causing arrhythmia. Findings of MERLIN TIMI 36 should mitigate this concern. However, studies specifically designed to evaluate the potential role of ranolazine as an antiarrhythmic agent are warranted.

Based on encouraging safety data shown in MERLIN TIMI 36 trial, CV Therapeutics has applied to the US FDA for first-line angina indication. It has also applied to the U.S. Food and Drug Administration (FDA) for two more indications, such as HbA1c reduction in coronary artery disease patients with diabetes and antiarrhythmic benefits. Based on initial evaluation of data presented, the FDA has accepted the application and has set the action date as 27 July 2008.

Among patients with ACS, ranolazine, an inhibitor of late INa, has antiarrhythmic effects as assessed by Holter monitoring. In particular, patients treated with ranolazine had fewer episodes of VT > 8 beats, SVT, and ventricular pauses > 3 seconds. Ranolazine was associated with a 37% reduction in risk of VT lasting >= 8 beats. Reduction in VT >= 8 beats was significant and consistent in high-risk subgroups based on ejection fraction, corrected QT interval, TIMI risk score, history of heart failure, and the presence or absence of ischemia on ECG.
