Cytotoxicity of Cratoxylum Formosum Subsp. Pruniflorum Gogel Extracts in Oral Cancer Cell Lines.

Background: Oral cancer is a health problem in Thailand. Cratoxylum formosum subsp. pruniflorum Gogel (Teawdang), normally consumed in northeast Thailand, has proven cytotoxic to cervical cancer cell lines including HeLa, SiHa and C-33A.

Anticancer Potential of Cratoxylum formosum Subsp. Pruniflorum (Kurz.) Gogel Extracts Against Cervical Cancer Cell Lines.

Background: Most northeast Thai vegetables may play roles in human health by acting as antioxidant and anticancer agents. Recent study showed that Cratoxylum formosum subsp. pruniflorum (Kurz.

Oxidative stress in cancer-bearing dogs assessed by measuring serum malondialdehyde.

Background: Oxidative stress, an excess of reactive oxygen species (ROS), causes lipid peroxidation resulting in cell and tissue damages. It may be associated with the development and progression of cancers in dogs. Malondialdehyde (MDA), the end product of lipid peroxidation, is commonly used as a marker of oxidative stress.

Monosodium glutamate (MSG) intake is associated with the prevalence of metabolic syndrome in a rural Thai population.

Background: Epidemiology and animal models suggest that dietary monosodium glutamate (MSG) may contribute to the onset of obesity and the metabolic syndrome.

Methods: Families (n = 324) from a rural area of Thailand were selected and provided MSG as the sole source for the use in meal preparation for 10 days. Three hundred forty-nine subjects aged 35-55 years completed the study and were evaluated for energy and nutrient intake, physical activity, and tobacco smoking.

Serum antioxidant levels and nutritional status in early and advanced stage lung cancer patients.

Objective: Malnutrition frequently occurs in lung cancer patients. We aimed to determine nutritional status and antioxidant and mineral levels in Thai patients with lung cancer.

Methods: A prospective study with matched case-control was conducted.

Comparative study for the detection of C4d in paraffin-embedded renal allograft biopsies by immunohistochemical techniques.

Background: Peritubular capillary complement C4d deposition is one of the criteria for diagnosis of acute humoral rejection in kidney allografts. Little information is provided for the effective technique to stain C4d protein.

Objective: To compare C4d staining results by using indirect immunofluorescence detection (IF) with immunoperoxidase methods (IP) in formalin-fixed, paraffin-embedded renal allograft tissue.

A preliminary study of thiamine status in northeastern Thai children with acute diarrhea.

This study is a preliminary determination of thiamine status in children with diarrhea and metabolic acidosis admitted to hospital. Children with diarrhea (N = 14; age 2 m-6 yr) were divided into 2 groups according to anion gap type; group 1 (21.4%) with a normal anion gap (5.

Serum beta-carotene, lycopene and alpha-tocopherol levels of healthy people in northeast Thailand.

Human serum contains many different antioxidants which may be important in the maintenance of antioxidant status. beta-carotene and lycopene are carotenoids with potent antioxidant activity. Carotenoids intake probably protects against cancers and may affect the risk of several chronic conditions.

Thiamine deficiency and parasitic infection in rural Thai children.

A study was carried out to determine whether thiamine deficiency in northeast Thailand is linked with parasitic infection. We assessed the thiamine status and tested for parasitic infections in 231 children between 6 and 12 years of age in Nam Phong District of Khon Kaen Province, Thailand. Thiamine deficiency [thiamine pyrophosphate effect (TPPE) > 20%] and parasitic infections (mostly Strongyloides stercoralis) were identified in 16 and 45% of the children, respectively.

Serum vitamin A and zinc levels of healthy people in northeast Thailand.

Background: Vitamin A and zinc are micronutrients which co-related to diseases afflicting northeast Thais. Vitamin A and zinc concentrations in serum have been studied in healthy northeast Thais between 23 and 75 years.

Methods: Vitamin A was analyzed by HPLC and zinc was determined by flame atomic absorption spectrometry.
