Zoned tourmaline （schorl-dravite） in the matrix of hydrothermal explosive breccia and ore veins in gold deposits, Chita region, Eastern Transbaikalia, Russia, are associated with Na- and K-rich porphyry-type subvolcanic intrusives. 61So values of tourmaline from three gold deposits （Darasun, Talatui, Teremkinskoye） are ＋8.3%, ＋7.6%, and --6.0% and calculated 6180 values of fluids respon- sible for the tourmalinization are ＋7.3%, ＋7.7%, and ＋4.2%, respectively. These data imply an igneous fluid source, except at the Teremkin deposit where mixing with meteoric water is indicated. Wide ranges of Fe3＋/Fetot and the presence of vacancies characterize the Darasun deposit tourmaline indicating wide ranges off（O2） and pH of mineralizing fluids. initial stage tourmalines from the gold deposits of the Darasun ore district are dravite or high mg schorl. Second stage tourmaline is characterized by oscillatory zoning but with Fe generally increasing towards crystal rims indicating decreasing temperature. Third stage tourmaline formed unzoned crystals with XMg （mole fraction of Mg） close to that of the first stage tourmaline, due to a close association with pyrite and arsenopyrite. From Fe^3＋/Fetot values, chemical composition and crystallization temperatures, logf（O2） of mineralizing fluids ranged from ca. -25 to 20, much higher than for the gold-bearing beresite-listvenite association, indicating that tourmalinization was not related to gold mineralization.

OBJECTiVE： Elevated natural killer lymphocyte cytotoxicity（NKc） has been linked with reproductive problems in women. Here we evaluate the potential benefit of cupping therapy（CT） in reproductionrelated immune ***： This was a pilot clinical study. Partici.ants were he althy fe male volunteers（n = 23） with elevated NKc, and received repeated CT 3 times over 5 d（inner pressure 40–50 kPa, 40 min; 12–1 5 cups）. Lymphocyte subsets, NKc and NK lymphocyte activity（NKa） were measured in blood on day 0（initial levels, before the first treatment） and days 3, 10 and 17 after the last CT treatment, using the K562-stimulated CD69 expression ***： As a result of CT manipulations NKa was reduced on days 3 and 10, and NK percentage was reduced on day 10. NKc was most sensitive to CT treatment, resulting in their decreased counts at 3, 10 and 17 d post CT. CT treatment decreased NKc in the majority of individuals（87%）, but the magnitude of the effect was variable. Out of 23 subjects 9（39.1%） had a 2–3 fold decrease of NKc on days 3, 10 and 17; 11（47.8%） started to show a decrease in NKc later, or more quickly returned to base levels; and only 3（13%） subjects displayed no effect of CT on NKc. Expectedly, no changes in T-cell subsets（CD3CD4, CD3CD8, HLADR, CD158a） were observed after ***： CT decreased NK cell numbers, their activity and cytotoxicity. Low cost, safety, noninvasive nature and ease of administration make CT a promising approach for NKc down-regulation.
