Drugs that slow or kill the novel coronavirus, called severe acute respiratory syndrome coronavirus 2, could save the lives of severely ill patients, but might also be given prophylactically to protect health care workers and others at high risk of infection. Treatments may also reduce the time patients spend in intensive care units, freeing critical hospital beds. Recovery from the disease depends mainly on the innate immunity of the patient. Patients who suffer much from COVID-19 are children, old people (over 65 years), those patients with chronic diseases (diabetes mellitus, hypertension, liver disease, kidney disease), obese patients, alcoholics, and smokers. About 80% of corona patients may overcome the infection, and less than 5% may pass into fatal complications. Patients immunity is the main weapon to fight the disease. The present herbal recipe was selected to support and maintain the innate immunity of the patient against corona virus disease-19. It is composed of 3 herbal materials: bee honey, Nigella sativa (black seed), and Acacia nilotica (Quardh).

Muscle fatigue is commonly pronounced in clinical aspects as exercise induced syndrome. In this review, we presents physical structure of muscle including actin and myosin arrangement for Excitation–contraction coupling and contribution of ions and other factors like O2, ROS, pH, Blood flow, lactate, inorganic phosphate, Heat shock protein for muscle contraction and fatigue development. Finally the EMG power spectrum characteristics also discussed before and after the fatigue development.

Background: Unregulated mining has the potential to release harmful substances into the soil, air, and water and this may be associated with negative health, social and environmental impacts. Inhalable dust is produced during processing, grading and during the transit by the vehicles. Epidemiologic data indicate that there are occupational hazards associated with stone crushing and inhalation of stone dust. Quarrying/stone crushing is increasingly becoming the main stay of Ebonyi State economy and major source of internally generated revenue yet there is little or no government policy on regulation and occupational safety. Aim: This study examined the effect of long time exposure to quarry dust on the Full Blood Count (FBC) of quarry workers at Okposi Umuoghara, Ezza LGA of Ebonyi State – Nigeria. Methods: Cross-sectional, descriptive and analytical study was carried out on 100 quarry workers; 36 males and 54 females (age; between 18-57 years) who were exposed to stone dust for more than one year and 84 age/sex matched workers not exposed to quarry dust as control. The haemoglobin concentration, haematocrit, total while blood cell and differential counts were estimated using standard methods. Results: Majority of the quarry workers in Okposi - Umuoghara Idustrial Estate were female, low income and uneducated who are not aware of the health implications of their carrier. There were significant differences in mean values of in Hb, PCV, and total WBC, relative netrophils, lymphocytes and eosinophil counts compared with control. The differential lymphocytes and eosinophil increased significantly (p > 0.05), while the Hb, PCV, total WBC and relative neutrophil count decreased significantly (P < 0.05). No significant variation in differential monocyte count was observed. Conclusion: The alterations in level of some haemotological parameters in exposed workers is an indication of effect of quarry dust on pathopysiology of blood and reticuloendothelia system of factory workers and in general human health. There is need for regular health evaluation of workers and education on the essential safety precautions through the use of personal protective equipment and more mechanized and safer means of stone processing.
