BACKGROUND AND OBJECTIVES: Myelo-suppression is the most common toxicity encountered in the oncology clinic today. This study was planned to investigate the possible protective and therapeutic role of the traditional Chinese Medicinal Herb; Astragalus Membranaceus (AM), on chemotherapy-induced myelosuppression. METHODS AND RESULTS: This study was carried out on thirty six adult male albino rats. They were divided into: Group I Control Group (n=6) received a vehicle of phosphate buffered saline (PBS) solution. Group II (n=12) were injected I.P. with cyclophosphamide (CY) for 3 days (gIIa n =6) and continued for one more week to receive AM orally (gIIb n=6). Group III (n=6) received CY I.P. together with AM orally for 3 days. Group IV (n=12) received AM orally for one week (gIVa n=6) and continued for extra three days receiving CY I.P. with AM orally (gIVb n=6). Blood samples were analysed for Total Leucocytic Count and Lymphocytic Count. Counting of CD34 +ve cells in bone marrow was performed by flowcytometry. Bone marrow sections were subjected to H&E stain as well as immunohistochemical staining for anti- CD20 antibody. The mean area % of cellular bone marrow regions occupied by developing haemopoietic cells, mean area of fat cells and mean number of CD20 immunopositive B lymphocytes in the bone marrow were measured by histomorphometric studies and statistically compared. AM proved to have a myelo-protective and myelo-therapeutic capacity, evidenced at both laboratory and morphological levels. CONCLUSIONS: The greatest myelo-potentiating effect of AM was achieved when supplied before and together with CY therapy.

Purpose:
The cow’s milk-related-symptom-score (CoMiSS) tool was developed as an awareness tool for the assessment of cow’s milk-related symptoms in infants or children.Fecal calprotectin (FC) is a noninvasive biomarker of gut inflammation that can be measured in serum and stool. This study aimed to investigate the relationship between FC levels and CoMiSS scores in infants with cow’s milk protein allergy.
Methods:
Infants (aged 6–12 months) who were allergic to cow’s milk protein were enrolled prospectively. Following completion of the CoMiSS scoring, the infants were divided into group 1 (positive CoMiSS scores ≥12) and group 2 (negative CoMiSS scores <12). FC was measured using immunoassay.
Results:
Of the 120 infants enrolled in this study, 60 (50.0%) had positive CoMiSS scores (group 1), while 60 (50.0%) had negative scores (group 2). The mean FC level was higher in the infants in group 1 than those in group 2 (2,934.57 µg/g vs. 955.13 µg/g; p<0.001). In addition, there was a positive correlation between FC and CoMiSS scores (R=0.168, p<0.0001). A FC level of 1,700 µg/g provided a sensitivity of 98.3%, specificity of 93.3%, and accuracy of 95.8% for the diagnosis of cow’s milk protein allergy (CMPA).
Conclusion
FC measurement may have a role in the assessing infants with CMPA.
