A study on quality of Paridis Rhizoma and consideration on standards of Paridis Rhizoma in Chinese Pharmacopoeia / 中国中药杂志

Thin layer chromatography, high performance liquid chromatography and multivariate statistical analysis were integrated in current study to provide a basis for the quality evaluation and the standard improvement of Paridis Rhizoma(Chinese name: Chong-lou). The results demonstrated that the primary saponins in the two authorized sources of Paridis Rhizoma were polyphyllinsⅠ, Ⅱ and Ⅶ, while the rhizome of Trillium tschonoskii an adulterant of Paridis Rhizoma was rich of polyphyllin Ⅵ. Therefore, the apparent content of polyphyllin Ⅵ plays a determinant role towards the source authentication of raw materials and decoction slices of Paridis Rhizoma, whose adulterants frequently occur in the market. Moreover, the contents of polyphyllin Ⅵ in the two authorized sources could meet the requirements of Chinese Pharmacopoeia. Therefore, we suggested that polyphyllin Ⅵ should not be omitted from the quality standard of Paridis Rhizoma in the Chinese Pharmacopoeia, and on the other side, polyphyllinsⅠ, Ⅱ and Ⅶ should be the eligible quality indicators. The study aims to sound information and evidences for the quality evaluation of Paridis Rhizoma, and also to provide a theoretical basis for the standard revision of Paridis Rhizoma in the future Chinese Pharmacopoeia.

Clinical Features of 46 Multiple Myeloma Patients with Different Renal Pathology / 中国实验血液学杂志

<p><b>OBJECTIVE</b>To explore the clinical features of multiple myeloma with different renal pathology, and to evaluate its prognosis.</p><p><b>METHODS</b>Clinical features and prognosis of 46 multiple myeloma patients with different renal pathology were analyzed retrospectively. According to renal pathology, the 46 patients were divided into 3 groups: cast nephropathy (24 cases), amyloidosis (15 cases) and other type (7 cases).</p><p><b>RESULTS</b>By durie-Salmon staging system, 70.8% cases (17/24) in the cast nephropathy group were in Phase III, 90.9% (20/24) were in subtype B, while in amyloidosis group 53.3% (8/15) were in Phase I, 40% (6/15) were in subtype B, and in other types group, 71.4% (5/7) were in phase III, 57.1% (4/7) were in subtype B, the differences among them were statisticaily significant (P < 0.05). In cast nephropathy group, the monoclonal immunoglobulin could not be detected in 75% (18/24) cases, which was light chain type, while immunoglobulin in amyloidosis and other type groups were mainly IgG type in 73.3% (11/15) and 71.4% (5/7) respectively, the difference among them also was statistically significant (P < 0.05). The median survival time of patients in cast nephropathy group was 11 months, while that in amyloidosis and other type groups was 19 and 18 months, the differences among 3 groups were not significant (P > 0.05).</p><p><b>CONCLUSION</b>In renal pathologic types, the cast nephropathy is the most common, followed by amylordosis. The multiple mycloma patients with defferent renal pathology show different clinical features. The multiple myeloma patients with renal amyloidosis have slighter clinical manifestations possibly with a better prognosis. Meanwhile, the non-amyloidosis types, especially cast nephropathy may predict a more serious manifications with poor prognosis.</p>

Effect of Cortisone and X-ray Irradiation on Mast Cells of the Adrenalectomized Albinor Rats

The effects of cortisone administration and whole body irradiation by X-ray upon mesenteric mast cells of intact and adrenalectomized albino rats were studied. In intact rats, the administration of cortisone (50mg./kg) and whole body irradiation by X-ray (800r) caused severe degranulation and disruption of mesenteric mast cells within 24 hours. However their degranulation and disrupting effects upon mesenteric mast cells were markedly inhibited after the removal of the adrenal gland. Although the adrenalectomy alone hardly caused these morphological changes of mesenteric mast cells of the albino rats. According to this experiment it is fairly clear that the effects of cortisone and whole body X-ray irradiation inducing degranulation and disruption of mesenteric mast cells of the albino rats, were not direct phenomena but they indirectly affected the mesenteric mast cells through some special mechanism mediated by the adrenal gland.
