The oil of garlic, Allium sativum L. (Amaryllidaceae), as a potential protectant against Anisakis spp. Type II (L3) (Nematoda) infection in Wistar rats.

The consumption of inadequately thermally treated fish is a public health risk due to the possible propagation of Anisakis larvae. The present study demonstrated the physiological and histopathological changes that accompanied an oral inoculation of crude extracts from fresh and thermally treated Anisakis Type II (L3) in rats. Worms were isolated from a marine fish and examined and identified using light and scanning electron microscopy. The study was performed in 6 rat groups: control (I), garlic oil (GO) inoculated (II), fresh L3 inoculated (III), thermally treated L3 inoculated (IV), fresh L3 + GO inoculated (V), and a thermally treated L3 + GO inoculated (VI) groups. Rats inoculated with fresh and thermally treated L3 showed abnormal liver and kidney functions associated with the destruction of normal architecture. GO produced a protective effect in rat groups inoculated with L3 extracts + GO via the amelioration of liver and kidney functions, which was confirmed by the marked normal structure on histology. Cooking of L3-infected fish induced severe alterations compared to uncooked fish. The administration of garlic before and after fish eating is recommended to avoid the dangerous effect of anisakids, even if they are cooked.

Abstract The consumption of inadequately thermally treated fish is a public health risk due to the possible propagation of Anisakis larvae. The present study demonstrated the physiological and histopathological changes that accompanied an oral inoculation of crude extracts from fresh and thermally treated Anisakis Type II (L3) in rats. Worms were isolated from a marine fish and examined and identified using light and scanning electron microscopy. The study was performed in 6 rat groups: control (I), garlic oil (GO) inoculated (II), fresh L3 inoculated (III), thermally treated L3 inoculated (IV), fresh L3 + GO inoculated (V), and a thermally treated L3 + GO inoculated (VI) groups. Rats inoculated with fresh and thermally treated L3 showed abnormal liver and kidney functions associated with the destruction of normal architecture. GO produced a protective effect in rat groups inoculated with L3 extracts + GO via the amelioration of liver and kidney functions, which was confirmed by the marked normal structure on histology.

Resumo O consumo de peixe inadequadamente tratado termicamente representa um risco para a saúde pública, com a possibilidade da propagação de larvas de Anisakis. O presente estudo demonstrou as alterações fisiológicas e histopatológicas acompanhadas de inoculação oral de extractos brutos de Anisakis tipo II (L3) frescos e termicamente tratados em ratos. Os vermes foram isolados de um peixe marinho, examinados e identificados por microscopia de luz e eletrônica de varredura. O estudo foi conduzido em 6 grupos de ratos: controle (I), óleo de alho (GO) inoculado (II), L3 fresco inoculado (III), L3 tratado termicamente inoculado (IV), L3 fresco + GO inoculado (V), e um grupo L3 + GO tratado termicamente inoculado (VI). Observou-se que ratos inoculados com L3 fresco e tratados termicamente mostraram funções hepáticas e renais anormais, associadas à destruição da sua arquitetura normal. GO produziu um efeito protector em grupos de ratos inoculados com extractos L3 + GO através da melhoria das funções do fígado e dos rins, o que foi confirmado pela estrutura normal marcada da sua histologia. A cozedura de peixes infectados com L3 induziu alterações mais graves do que os peixes não cozidos. Recomenda-se a administração de alho antes e depois do consumo de peixe, para evitar o efeito perigoso dos anisakids, mesmo que sejam cozidos.

The Saudi Abnormal Glucose Metabolism and Diabetes Impact Study (SAUDI-DM).

BACKGROUND AND OBJECTIVES: Saudi Arabia underwent opulence-driven socio-cultural and lifestyle changes leading to soaring rates of diabetes mellitus. This study exposes the epidemiology of abnormal glucose metabolism namely: diabetes and impaired fasting glucose (IFG) in 13 administrative regions of Saudi Arabia. DESIGN AND SETTINGS: This is a nationwide, household, population-based cross-sectional study that was conducted through primary health care centers during the period 2007-2009. PATIENTS AND METHODS: A nationwide, household, population-based cohort of 53370 participants aged 0-100 years adjusted to be compatible with population census was interviewed and anthropometric measures were collected. Fasting blood sample was used to screen for IFG and diabetes. RESULTS: The overall prevalence of abnormal glucose metabolism was 34.5%, which included 22.6% patients with IFG, 11.9% patients with diabetes, and 6.2% patients who unaware of their disease. Diabetes prevalence was 40.2% for subjects aged >=45 years and 25.4% for those aged >=30 years that decreased to 11.9% when the full age spectrum was considered. Type 1 diabetes prevalence was 0. 8%, contributing only to 6.6% of the total population of patients with diabetes. The top 5 regions with the highest abnormal glucose metabolism prevalence were Makkah (43.4%), Aljouf (41.7%), Eastern region (37.16%), Madinah (35.4%), and Qassim (33.7%). Urbanization, age, and obesity were behind the wide variations in diabetes and IFG prevalence in the 13 regions. CONCLUSION: Abnormal glucose metabolism has reached an epidemic state in Saudi Arabia, where one-third of the population is affected and half of diabetic cases were unaware of their disease. This observation warrants an urgent strategy for launching diabetes primary prevention and screening programs.
