    Notes: The whole body extracts (WBEs) of female and male cockroaches (Periplaneta americana; Pa) were prepared separately to study the specific and/or shared allergenic and antigenic components in the two sexes. These two extracts were skin-tested on 170 respiratory allergy patients and 52 (30–6%) of them elicited a markedly positive cutaneous reaction (2+ to 4+) to any one or both the WBEs. Of these 52 patients, 32 (61·5%) produced a 2+ to 4+ response to only one, and the remaining 20 (38·5%) to both the extracts. In female and male RASTs to Pa both the extracts produced dose-related inhibition. Using rabbit anti-Pa female serum: (1) immuno-diffusion experiments resulted in lines of identity with the two extracts, and (2) the two-dimensional immunoelectrophoresis of Pa female and Pa male WBEs elicited 12 and nine precipitin peaks, respectively. In partial purification studies, only fraction Pa(F)III (∼ 50 kD) of Pa female WBE and Pa(M)I (〈inlineGraphic alt="geqslant R: gt-or-equal, slanted" extraInfo="nonStandardEntity" href="urn:x-wiley:09547894:CEA59:ges" location="ges.gif"/〉 600 kD) and Pa(M)III (∼ 50 kD) fractions of Pa male WBE revealed significant allergen activity both on skin testing and also in RAST inhibition studies. These results provide evidence for the presence of shared as well as specific allergenic and antigenic components in the two sexes of American cockroach.

    Notes: Abstract In a review of 77 HIV positive children seen between 1981 and 1990, 32 were diagnosed as having lymphocytic interstitial pneumonitis). Four of the LIP group developed bronchiectasis, a finding not previously reported. The precise factors leading to the bronchiectasis are unclear. All patients had chronically consolidated lung with volume loss. A history of recurrent bacterial superinfection was not noted in any of the cases. With more cases of HIV positive children living longer, bronchiectasis, long known to occur in primary immunologic disorders, will probably be more frequently noted.

    Isolation, characterization, and properties of a trypsin-chymotrypsin inhibitor from amaranth seeds (1996)

    Notes: Abstract A trypsin-chymotrypsin inhibitor was isolated from the seeds of amaranth—a highly nutritious protein source. The purification of the inhibitor (AmI) was carried out by affinity chromatography on trypsin-Sepharose and by HPLC. AmI is a single-chain protein of 8 kD, as determined by electrophoresis on SDS-polyacrylamide gels and by gel exclusion on Sephadex G-50 column. It is stable at neutral and alkalinepH and is relatively thermostable. AmI inhibits trypsin and chymotrypsin from the digestive system of insects such asTribolium castaneum andLocusta migratoria, supporting the hypothesis that inhibitors may have evolved as defense mechanisms of seeds against insects. AmI lost its inhibitory activities when submitted to limited proteolysis with trypsin, while limited proteolysis with chymotrypsin had almost no effect. The partial amino acid sequence of 45 amino acids from the amino terminus of AmI differs significantly from the known sequences of legume-seed and cereal-grain protease inhibitor families. Differences in the chemistry at the inhibitory site(s) and in the amino acid sequence of AmI in comparison to that of other cereal and legume inhibitors suggest that AmI is a member of a new family of serine protease inhibitors. AmI was found to inhibit the anchorage-independent growth of MCF-7 breast cancer cells, suggesting that AmI may have anticarcinogenic activity.

    Notes: Abstract Of 1362 sheep examined during two years in Fars Province of Iran, 786 (57.7%) were positive for Sarcocystis spp. The prevalence was significantly higher (p〈0.05) in animals owned by nomadic Assyrians (67.95%) than in those owned by local people (41.86%). More of the animals above 2 years age were infected (69.98%) than young ones (30.02%). Females had a higher prevalence of infection (61.07%) than males (38.93%) but most of the males were younger. There was no variation in the infection rate during spring, summer or autumn, but it was low in winter. The species observed were Sarcocystis gigantea, predominantly in oesophagus, S. medusiformis, mainly in diaphragm, S. tenella in the oesophagus, diaphragm, tongue and heart, and S. arieticanis in the oesophagus, tongue and occasionally in the diaphragm. In transmission studies, the prepatent period for S. gigantea and S. medusiformis and for the two microscopic species was 11–13, 10 and 8–12 days, respectively. The infection could not be transmitted to hamsters and guinea-pigs. The macroscopic species were almost non-pathogenic but were responsible for economic losses because of rejection of carcases or parts thereof at slaughter. The microscopic species caused tissue damage to the affected organs, resulting in haemorrhages, mononuclear infiltration and necrotic changes.

    Epidemiological correlates between consumption of Indian chewing tobacco and oral cancer (1990)
    Springer

    Notes: Abstract The problem of cancer is universal; the only variation occurs in the type, site or other clinicoepidemiological parameters. Peculiarly enough, oral cancers caused by chewing tobacco are common in India and some parts of the Indian sub-continent. Oral cancers caused by other carcinogens are not common in these areas. The present study shows a significant association (P L 0.001) between the use of Indian chewing tobacco and oral cancer. Number of quids, mean quantity of tobacco and mean duration of keeping the quids in the mouth had direct dose and effect relationships in causation of oral cancer. A dose of 10 gms of chewing tobacco for about 26 years was observed to have produced cancerous lesions in the buccal cavity.

    Notes: Abstract Aerial prevalence of clinically important thermophilic actinomycetes and occurrence of precipitating antibodies against them in sera of 153 exposed workers have been reported. The study was carried out in two cane sugar mills namely, the Upper Doab Sugar Mills and the Ramala Sugar Mills, located in north-west India. In both the sugar mills,T. sacchari was the predominant species, it accounted for 55.1% and 50.3% of the total population of thermophilic actinomycetes, followed byT. vulgaris (19.7% and 23.7%),T. thalpophilus (21.1% and 17.1%),Saccharomonospora viridis (3.4% and 5.0%) andSaccharopolyspora rectivirgula (Faenia rectivirgula) (0.7% and 3.9%), respectively. Precipitating antibodies against thermophilic actinomycetes were demonstrable in 34 (22.2%) workers;T. sacchari alone accounted for 20 of the positive precipitin reactions, followed byS. rectivirgula in 10. The mean absorbance values for IgG antibody activity againstT. sacchari as well asS. rectivirgula were found to be elevated significantly in the symptomatic workers than in the asymptomatic workers (p〈0.05) or unexposed controls (p〈0.001). However, the difference in IgG antibody activity was insignificant between precipitin-positive symptomatic workers and precipitin-positive asymptomatic workers. The results indicate that clinically important thermophilic actinomycetes are widely prevalent in cane sugar mills, andT. sacchari andS. rectivirgula are the major species involved in the sensitization of the bagasse workers in India.

    Notes: Abstract The study was prompted by the lack of information on the role of thermophilic actinomycetes in hypersensitivity pneumonitis in India. It reports the occurrence of precipitating antibodies against clinically important thermophilic actinomycetes in the sera of a population sample of dairy herd workers, Nangali, Delhi. Of 112 workers investigated, 28 (25%) showed precipitins againstFaenia rectivirgula, 4 (3.2%) againstSaccharomonospora viridis, 2 againstThermoactinomyces thalpophilus and one each againstT. vulgaris andT. sacchari. The results of enzyme-linked immunosorbent assay (ELISA) indicated that IgG antibody activity againstF. rectivirgula was significantly higher in the symptomatic group than in the asymptomatic group (p〈0.05) of workers and the controls (p〈0.01). Significant difference inF. rectivirgula IgG activity was also obtained between the precipitin-positive symptomatic group and the precipitin-positive asymptomatic group (p〈 0.05). In strong contrast, the IgG antibody activity againstT. thalpophilus was found to be uniformly low. A limited aeromicrobiological sampling of the dairy farm revealedS. viridis (55.8%) to be the commonest species followed byT. vulgaris (19.2%),T. thalpophilus (18.5%),F. rectivirgula (5%) andT. sacchari (15%). On the basis of suggestive clinical and laboratory findings, farmer's lung disease was suspected in four dairy herd workers. A comprehensive clinical evaluation including pulmonary function studies on the dairy herd workers and their long-term follow-up is indicated to determine the extent of respiratory morbidity caused byF. rectivirgula, S. viridis, T. thalpophilus, T. sacchari andT. vulgaris in India.

    Notes: Summary Chromatographic separation of racemic amines, carboxylic acids and alcohols can be achieved with excellent resolution as measured in terms of the chromatographic separation factor α by derivatization with a homochiral oxazolidin-2-one easily prepared in three steps fromendo-borneol. The resolved materials can be isolated in excellent yields by cleavage of the resultant diastereomers using conventional methods, which also allow recovery of the chiral resolving agent for re-use.
