Abstract

There is no doubt that advances have been made and significant improvement reported on the application of orthodox therapies in the management and treatment of various acute and chronic diseases. However, different reports seem to show that orthodox therapies are restricted by mechanisms of action, which tend to focus on the symptoms of the disease instead of the main cause. On the other hand, throughout history, African traditional medicine (ATM) using products majorly from medicinal plants have been applied to alleviate symptoms of various diseases such as diabetes, hypertension, infertility, parasitic, bacterial, viral and fungal infections. Globally, information in respect of certain medicinal plants and their activities has been passed on from generation to generation. Fortunately, scientific studies have been able to confirm some of these claims and established the importance of medicinal plants in health care. Although African traditional medicine has contributed significantly to health care in Africa with over 80% of the population using African traditional medicine for their primary health service, it is faced with some challenges in term of its regulation and practice. Indiscriminate or non-regulated applications of various herbal medicines has put the health of people especially in African countries at the risk of toxicity or adverse effects or even death. It is for this reason that this paper examines the relevance of African traditional medicine, its regulation, the challenges associated with its regulation and the way forward.

Abstract

This paper reviews the importance of honey bee as pollinator of agriculture crops, fruit, vegetables, seeds etc. and losses in agriculture, honey bee and honey production due to use of chemical pesticides. Honey bee (Hymenoptera: Apidae) is economically important insect. Honeybees are existing all around world excluding extreme Polar Regions.  Honey bees (Apis mellifera) add approximately US $200 billion to the global economy every year, mainly through crop pollination. Productivity worth of pollination dependent crops equal to US$ 1590 million in Pakistan where 61 main pollinate crops are considered as foodstuff  (26 fruits, 19 vegetable, 7 oilseeds, 4 grain legumes, 2 flavoring crops and 3 nut shrubs) depend on  honey bee pollination. Honey bee population is declining with alarming speed all around the world and it is endangering global food security because one third of agriculture production depend upon on pollination particularly by honey bee. Current reduction in honey bee population for agriculture pollination is threatening to nuts, fruit, vegetable and seed production in Pakistan. Several factors responsible for decline of honey bee colonies including climate change, predation by other insects, air pollution, ecosemiotic collapse, the alteration of the bee microbiome, electromagnetic radiation from the sun, expose to initial life stress, nano materials, and biochemical pesticides, diseases, parasites surroundings of honey bees. The toxic chemicals are transported in hive through the pollen and nectar which may destroy the entire honey bee colony. Pesticides pattern applied in agriculture have been changed in last decade. This review research indicates how pesticide is used in agricultural crops for control of pests affecting on honey bee health and decline of bee populations. Then concludes with intensive studies on current management protocols would support in procedure formulation and resolution making polices regarding to shelter honey bees and management of pollination for agriculture purpose, which is lacking.

Abstract


Arsenic is natural metalloid which is present in the universe everywhere. It is used for different insecticides and pesticides preparation. Poisoning of arsenic is a major issue that affects different species. Its occurrence is related to contamination of feed and water; therefore, it is matter of concern globally. However, its level of toxicity is increasing very rapidly in Asian countries especially Bangladesh, India and Pakistan. Its increasing level of arsenic in ground water is the major source of poisoning to human and animals. In addition, the contact of animals to arsenic lead to absorption body and accumulation in vital organs like liver and kidneys that may resulted to carcinogenic development. Elimination of absorbed arsenic in environment through excretions of animals is also one way to increase its level in water/soil. The objective of this review is to gather the information about arsenic toxicity occurrence by natural or experimentally ways and changes occurred in suffered animals related to pathological or biochemical.

ABSTRACT

 

Zinc (Zn) is a micronutrient, essentially required by plants, animals and humans. Zn deficiency in humans due to the consumption of food with inadequate Zn content is of global concern. Approximately, one third of poor world’s population is at high risk of Zn deficiency due to its reliance on cereals for daily caloric requirements. The cereals, generally grown on calcareous soils have low grain Zn. The major reason of lower Zn content in cereals is poor Zn bioavailability induced by various soil and/or crop management factors.  The factors responsible for low grain Zn are high soil pH, low organic matter, salinity/alkalinity, water logging, and poorly managed soil fertility. Due to its critical role in growth and development of humans, food with adequate Zn content is mandatory. This situation demands some effective strategies for the enhancement of grain Zn content to overcome human Zn deficiency. Zinc supplementation of food, Zn pills, breeding of high Zn uptake species, and biofortification through fertilizers are being employed to address the issue. Among all strategies, Zn biofortification through fertilizers is an effective and economical technique. Mineral Zn fertilizers are applied alone or in combination with organic and biofertilizers. Integrated use of mineral, organic and biofertilizers improves Zn uptake and assimilation in cereals grains. Nanotechnology and enrichment/coating techniques are also effective to enhance grains Zn. This review critically discuss the efficiency of various strategies to promote Zn availability and uptake by plants that assure food and nutrition security.  Zn enriched/coated urea is considered an effective tool to ensure crops with optimum concentration of Zn for human consumption.
