Levels, Complement Activity and Polymorphisms of Mannan-Binding Lectin in Patients of Bronchial Asthma with Allergic Rhinitis

Activation of complement pathways, leading to production of C3a and C5a anaphylatoxins, has been postulated in the pathogenesis of asthma and allergic airway inflammation. The present study was undertaken to investigate the role of mannan-binding lectin (MBL), an initiator of the lectin pathway of complement, in asthma and allergic rhinitis. MBL levels and MBL-induced complement activity were determined in 19 patients of bronchial asthma with allergic rhinitis and 20 unrelated, age-matched controls of Indian origin. MBL levels and activity were correlated with percent eosinophilia and percent predicted FEV1 values of the patients. Association of single nucleotide polymorphisms (SNPs) in exon 1 and intron 1 of the MBL with the disease, clinical markers, MBL levels and MBL-induced complement activity was analysed using standard statistical tools. Significantly higher MBL levels and activity were observed in patients of bronchial asthma with allergic rhinitis as compared to the controls. We identified five SNPs, of which two, A816G in exon 1 and G1011A in intron 1 of the MBL, were novel. SNP G1011A was significantly associated with the disease ( P =  0.0024, OR = 5.8696, 95% CI: 1.7316 < OR < 19.8963). Individuals with 'A' allele at position 1011 showed increased MBL levels, activity and disease severity. Our results suggest that 'A' allele at position 1011 leading to high MBL levels and complement activity may be contributing to the severity of bronchial asthma and allergic airway inflammation.     

Deterioration in quality of life and depressive symptoms during radiation therapy for head and neck cancer.

OBJECTIVE: The aim of this study was to assess the quality of life and psychologic profile during radiation therapy for head and neck cancer. STUDY DESIGN AND SETTING: The University of Washington QoL instrument and the Hospital Anxiety and Depression Scale were administered to 202 patients at two or three time points during radiation therapy. RESULTS: A total of 118 (54.6%) patients completed the questionnaires at the beginning and at the end of the study. A mid-treatment dataset was also available for 67 (31.0%) patients. There was a statistically significant deterioration in composite QoL scores (P < 0.000) and a statistically significant increase in depression (P < 0.000). There was no difference in anxiety levels (P = 0.276). CONCLUSION: Patients undergoing radiation are increasingly depressed as treatment progresses, with worsening QoL during the treatment. SIGNIFICANCE: This study underlines the need for good psychologic support during radiation therapy in head and neck cancer.     

Elevated alpha-fetoprotein and a normal fetal sonogram: association with placental abnormalities

This report documents the outcome of 25 pregnancies with elevated serum alpha-fetoprotein levels on two separate samplings despite normal anatomic appearance of the fetus on a detailed "consultative" sonographic examination. Six of these also had elevated amniotic fluid alpha-fetoprotein. All fetuses in this series were anatomically normal at time of delivery; one aborted fetus was triploid. Of the 25 pregnancies, 16 had sonographically demonstrable placental hemorrhage, eight retroplacental and eight subchorionic. One had hydropic changes in the placenta associated with triploidy. Of the subgroup of six pregnancies in which both serum and amniotic fluid values were elevated, one had a retroplacental hemorrhage, one had a subchorionic hemorrhage, and one had diffuse hydropic changes in the placenta. A control group of 112 patients with normal alpha-fetoprotein levels yielded four with small (less than 2 cm3) subchorionic hemorrhage. The occurrence rate of placental hemorrhage in women with elevated alpha-fetoprotein and normal fetus was 64%, whereas the control group of patients with normal alpha-fetoprotein had a 3.6% occurrence rate of placental hemorrhage. Sonographically detectable placental abnormalities may be associated with elevated alpha-fetoprotein in serum and/or amniotic fluid samples. Such abnormalities may occur because of fetomaternal admixture associated with placental hemorrhage and/or intraamniotic bleeding resulting from subchorionic hemorrhage.     

Tinea corporis caused by Microsporum canis: Report of a Nosocomial outbreak

In an unusual nosocomial outbreak, 13 staff and 11 patients in an acute and chronic health care facility were infected with the zoophilic dermatophyte, Microsporum canis. The dermatophyte was apparently introduced into the facility by a single infected patient. Likely modes of subsequent disease transmission include person-to-person contact, handling of contaminated laundry, and use of a shared razor. Infection control measures for managing such outbreaks are discussed.

In vitro Propagation of Valeriana wallichii

A tissue culture procedure has been developed for the rapid multiplication of VALERIANA WALLICHII D C. through shoot tip and axillary bud explants. MS medium containing Kn or BAP (5.0 mg/l (-1)) in combination with IAA (1.0 mg/l (-1)) induced an optimal growth of shoots within 6-8 days from both apical and axillary bud explants. The roots developed on the same medium within 2-3 weeks. Hardening of IN VITRO grown plantlets in pots under glass-house conditions was dependent upon the temperature and humidity. A cold-temperate climate favoured early establishment. Following the given procedure, a large number of plants have been established under field conditions at two locations. The method has implications in the early introduction of an elite population as well as its improvement.
