Carcinogenicity of lifelong administration of capsaicin of hot pepper in mice.

Capsaicin was administered in a semisynthetic powdered diet at 0.03125% level for the lifespan of Swiss mice starting from 6 weeks of age. As a result of C treatment, tumors of the cecum were induced in 22% of females and 14% of males, whereas the corresponding tumor incidences in untreated female and male controls were both 8%. Histopathologically, the tumors were classified as benign polypoid adenomas. Capsaicin is the main pungent principle of hot pepper, which is consumed in high quantities by humans worldwide. The capsaicin content of some chili varieties ranges up to 0.53%.

Quantitative fluorodensitometric determination and survey of aflatoxins in nutmeg.

A study is presented for the quantitative fluorodensitometric analysis of aflatoxins in spices, in particular nutmeg (Semen myristicae). Samples were extracted with chloroform, followed by silica gel column cleanup according to the AOAC officail first action method, 26.019(a), and by 2-dimensional thin layer chromatography according to the antidiagonal technique. The method includes a confirmatory test for aflatoxins by hemiacetal formation. The concentrations of aflatoxins in samples were determined by measurement of the fluorescent intensities of the separated aflatoxin spots from sample and standards on the same chromato-plate with a reflectance flying-spot sensitometer. With such a technique, a coefficient of variation value of 5.22 plus or minus 1.24% (P = 99%) was calculated for a series of 5 standard B-1 spots and averaged for 13 TLC plates, demonstrating the precision of the chromatographic and densitometric procedures. An average recovery of 108.4 plus or minus 5.8% (P = 95%) was obtained for 11 spiked nutmeg extracts (5.0-20.0 mu-g B-1 added/kg), whereas an average recovery of 92.6 plus or minus 4.9 (P = 95%) was established for 13 spiked nutmeg samples (5.0-20.0 mu-g B-1 added/kg). The coefficient of variation of the complete analytical procedure for ground nutmeg was 8.80%. In a survey on the occurrence of aflatoxins in 40 commercial nutmeg samples (covering 12 different brands) in The Netherlands, aflatoxins were detected in 30 ground samples (32 ground samples analyzed) in concentrations ranging from 1.0 to 23.2 mu-g B-1/kg or 2.7 to 36.5 mu-g B-1 + B-2 + G-1 + G-2/kg, whereas no aflatoxins were present in whole nutmeg kernels (8 samples analyzed). The lowest level of detection was 1.0 mu-g B-1/kg. In addition, 50 commercial spices consisting of 19 different types of commodities other than nutmeg wer assayed for aflatoxins according to the same procedure. No aflatoxins were detected in these samples, with the exception of 1 sample of bay leaf which contained 5.1 mu-g B-1/kg.

Organochlorine pesticide residues in different Indian cereals, pulses, spices, vegetables, fruits, milk, butter, Deshi ghee, and edible oils.

A total of 244 samples of cereals (wheat flour, rice, and maize), pulses (arhar, moong, gram, lentil, and black gram), spices (turmeric, chili, coriander, and black pepper), vegetables (potato, onion, spinach, cabbage, brinjal, and tomato), fruits (mango, guava, apple, and grape), milk, butter, Deshi ghee, and edible oils (vegetable, mustard, groundnut, and sesame) collected from different cities of Northern Province (Utter Pradesh) were analyzed by gas liquid chromatography for the presence of organochlorine pesticide residues. Residues of hexachlorocyclohexane (HCH) and 2,2-bis(p-chlorophenyl)-1,1,1-trichloroethane (DDT) were detected in about 85% of the total samples of cereals, spices, milk, butter, Deshi ghee, and edible oils analyzed in the present study. However, the residue levels were either very small (less than 0.06 ppm) or not detected at all in pulses, vegetables, and fruits as compared with very high concentrations in wheat flour (4.42 and 0.12 ppm), butter (1.19 and 4.85 ppm), mustard oil (1.26 and 2.42 ppm), Deshi ghee (1.10 and 3.84 ppm), vegetable oil (1.02 and 0.59 ppm), groundnut oil (0.51 and 1.49 ppm), and chili (0.48 and 1.92 ppm). The levels of HCH and DDT residues detected in rice, maize, turmeric, corlander, black pepper, and all the vegetables and fruits were also lower than those found in wheat flour, oil, and fat samples analyzed in the present study. These findings suggest that a restricted and controlled use of such persistent pesticides may be useful for decreasing their contamination levels in different food items.

[Substances harmful for the gastric mucosa].

Gastroduodenal mucosa has a self-defense capacity against a wide range of potentially harmful exogenous and endogenous agents. It has been proven that certain diet compounds damage gastric mucosa, which explains--at lest partially--the regional variations in the incidence of peptic ulcer. Ethanol blocks the defense mechanisms of gastric mucosa and induces the onset of acute lesions, but there is no definite proof to show that ethanol ingestion helps produce the onset of peptic ulcer. It has been confirmed that tobacco negatively affects the healing and relapse of ulcers. From an epidemiological point of view, the controversy of the relationship between tobacco abuse and peptic ulcer genesis is still ongoing. Non-steroid anti-inflammatory non-acid soluble produces lesions acute and chronic) in gastroduodenal mucosa. They can reactivate old lesions and increased the risk of complications. Aspirin is the most harmful compound in this pharmacologic group. Paracetamol is the compound which has the safest spectrum. The harmfulness of steroids is still being discussed, however, it is accepted that they have a rapid effect on gastric mucosa in relation to dosage and duration of treatment.

The effect of spices on cholesterol 7 alpha-hydroxylase activity and on serum and hepatic cholesterol levels in the rat.

The effect of feeding curcumin, capsaicin, ginger, mustard, black pepper and cumin on cholesterol and bile acid metabolism was studied in rats. The activity of hepatic cholesterol-7 alpha-hydroxylase, the rate-limiting enzyme of bile acid biosynthesis, was significantly elevated in curcumin (turmeric), capsaicin (red pepper), ginger and mustard treated animals. The enzyme activity was comparable to controls in black pepper and cumin fed rats. Serum and liver microsomal cholesterol contents were significantly higher in the curcumin and capsaicin treated animals. Thus, this study has suggested that the spices--turmeric, red pepper, ginger and mustard can stimulate the conversion of cholesterol to bile acids, an important pathway of elimination of cholesterol from the body. However, simultaneous stimulation of cholesterol synthesis by the spice principles--curcumin and capsaicin suggests that there may not be any significant contribution of stimulation of bile acid biosynthesis to the hypocholesterolemic action of these spices, and the latter action may solely be due to interference with exogenous cholesterol absorption.

[Food allergies 1983-1987].

229 patients who showed an immediate-type allergy to one or more specific foodstuffs diagnosed from 1983 to 1987 at the Allergy Unit of the Department of Dermatology, Zurich University Hospital, have been studied. Of these predominantly adult patients, 66 (28.8%) were male and 163 (71.2%) female. 70.7% of the food allergic patients also showed one or more atopic manifestations, in particular 53.3% a pollinosis. The food-induced symptoms included involvement of the skin (rashes, urticaria, angioedema) (46.4), the respiratory tract (asthma, rhinorrhea) (24.1%) and the gastrointestinal tract (21.8%). 14.4% reacted with anaphylactic shock. Generally the patients showed involvement of two or more organs. In only 7% of all cases was food allergy responsible for a chronic allergic condition such as urticaria, asthma or intestinal symptoms. Concerning diagnostic procedures, a careful case history and various techniques of skin testing, particularly with raw foods, are helpful. RAST was negative in more of the half of the diagnosed cases. Confirming previously published work, food allergens were mainly found among vegetables, such as celery with 44.5%, followed by carrots (14.4%) and spices (16.6%). In these cases there were cross-reactivities between birch or mugwort pollens. Cheese and milk allergies (14%) were present in patients without previous atopic manifestations. We confirm that the so-called "celery-carrot-mugwort-spice-syndrome" is more frequent in females (81.4%) than in males. In 24 cases celery-spice sensitization was responsible for severe anaphylactic reactions.

Bradshaw lecture, 1976. Thyroid medullary carcinoma.

The main characteristics of medullary carcinoma of the thyroid are its non-follicular histological appearance, resulting from its origin from the parafollicular C cells, its secretion of calcitonin, providing a relatively simple diagnostic test, and its equal sex incidence, in contrast to all other diseases of the thyroid. Sporadic cases are seen and it occurs in familial groups, with autosomal dominant inheritance, when it is associated with phaeochromocytoma and parathyroid hyperplasia to form the second type of multiple endocrine adenomatosis (MEA2). These last features make it necessary in every case of medullary carcinoma of the thyroid to examine other members of the family and to investigate the possibility of concomitant adrenal and parathyroid disease. The priorities of treatment when these are present and the indications for total thyroidectomy are discussed.

[Variations in the individual consumption of table salt with or without chili in food, in a community of México].

The present study was carried out in a rural community in the central plateau of Mexico, with the objective of estimating the mean daily consumption of table salt at the family and individual level, and to determine if the individual taste to salt added to the food at the table, varied with the presence or absence of a hot species, "chile", to the food. Our results showed variability in three "barrios" of the community, which go from the central, more urban-type (Temascalcingo) to an intermediate-type (Boquí), and to a more rural-type (Bonshó), showing the highest mean consumption of salt at the family level in the most urban barrio (47.2 g/day), while the mean family consumption in the other two barrios (28.2 and 33.9 g/day, respectively) was lower. At the individual level, there were differences in salt consumption associated to sex and age. The highest consumptions were found in the more urban-type barrio, in which men in the 15-22 year-old group consumed a mean of 9 g/day, and women in the 7-14 year-old group consumed a mean of 6.37 g/day. When the individual taste for salt added to foods commonly prepared in the community were studied, we found a statisticaly significant difference in individual taste associated with the presence or absence of chile in the food. In two of the study meals (breakfast and lunch) the total grams of salt added to the food which did not contain chile was significantly higher than the salt added to the food which contained chile, suggesting that the presence of the specie may account for a great part of the need to enhance food flavor. This in turn could explain the smaller consumption of table salt in the more rural-type section of the population noted in the first part of the study, in which families tend to add more chile to their food than in the urban-type settings.

Contact and systemic contact-type dermatitis to spices.

Contact and systemic contact-type dermatitis reactions to spices such as nutmeg, mace, cardamom, curry, cinnamon, and laurel may be rare but may well be overlooked. In our experience, patch testing with these spices "as is" is very useful; if there is a positive reaction, testing with dilutions is helpful. Scratch-chamber testing often leads to false-positive irritant reactions. As Hjorth and Niinimäki have pointed out, a positive test to balsam of Peru may indicate a spice allergy, but the absence of such a reaction does not rule it out. In all the cases in our experience, the careful drafting of the anamnesis or case history was critical in the diagnosis.

Dry rehydratable film for enumeration of total aerobic bacteria in foods: collaborative study.

A rehydratable dry-film plating procedure for aerobic plate counts has been compared to the standard agar plate method (966.23B and C, 15th ed.; 46.014-46.015, 14th ed.) in a collaborative study by 12 laboratories. Each laboratory analyzed the normal microflora of 3 samples in duplicate for 6 products. The aerobic plate counts ranged from 1.0 x 10(3) to 1.0 x 10(8) cfu/g. The products were flour, nuts, frozen raw shrimp, spice, frozen raw ground turkey, and frozen and refrigerated vegetables. Repeatability standard deviations of the 2 methods did not differ significantly for 13 of 18 test samples. For 1 shrimp and 2 turkey samples, the dry-film method had lower repeatability variances (P less than 0.05) and for 1 spice sample the agar method had lower repeatability variances (P less than 0.05). Relative standard deviations of repeatability were between 1.7 and 15.5% for the dry-film method and 1.2 and 16.0% for the agar method. Relative standard deviations of reproducibility ranged from 2.4 to 23.4% for the dry-film method and 2.3 to 18.8% for the agar method. The dry rehydratable film method has been adopted official first action for determination of the aerobic plate count.

Spice of life: a strategy to enhance dietary compliance.

A creative teaching strategy was implemented to stimulate patients' motivation to incorporate learned dietary concepts into their daily life-style. Thirty-five hemodialysis patients were given a pamphlet that described herbs and spices to enhance the flavor of specific foods and 25 sample seasoning packets for their experimentation. Most stated that the pamphlet was helpful (82.9%) and use of the spices made the diet palatable 75% or more of the time (93.4%).

Plant products as protective agents against cancer.

Out of various spices and leafy vegetables screened for their influence on the carcinogen-detoxifying enzyme, glutathione-S-transferase (GST) in Swiss mice, cumin seeds, poppy seeds, asafoetida, turmeric, kandathipili, neem flowers, manathakkali leaves, drumstick leaves, basil leaves and ponnakanni leaves increased GST activity by more than 78% in the stomach, liver and oesophagus, - high enough to be considered as protective agents against carcinogenesis. Glutathione levels were also significantly elevated in the three tissues by these plant products. All of them except neem flowers, significantly suppressed (in vivo) the chromosome aberrations (CA) caused by benzo(a)pyrene in mouse bone marrow cells. Multiple CA and exchanges reflecting the severity of damage within a cell were significantly suppressed by these nine plant products. The results suggest that these nine plant products are likely to suppress carcinogenesis and can act as protective agents against cancer.
