    Fossil bone and tooth samples from Zhouk oudian Loc. 1 were dated with uranium seriesdating. The data show that the ages of lower part of second and fourth layers were about 270and 300 ka respectively. The age of V skull excavated from the third layer, Locus H, should ,be about 290 ka.

    This paper described the incidences of the caries and periodontitis of 161 mandibles fromthe neonlithic site in Xiawanggang, Xichuan, Henan, and discussed the relationship between thefrequence of dental disease and the various localities, sex and age. In addition, the tooth wearand the abnormal cups and the root diseases were also scored.
    The results showed that the frequence of the caries and periodontitis had no clear asso-ciation with different localities, sex and age. But periodontitis is considered to be strongly associated with age.

    The first rare Jk(a-b-) type in China was found in Han, Henan Province, but no moreJk(a-b-) in the proband's family. Her parents and sibs were Jk(a+b-) type and her hu-sband and children were Jk(a-b+) type. The second Jk(a-b-) was found in Hakka, MeiCounty, Guangdong Province, four months later. This proband is a young unmarried woman.No antibody was found in both of these two proband' sera. Up to now Jk(a- b- ) phenotypefrequency in Chinese is 0.03%, and the gene frequency is 0.0202.

    A survey on taste sensitivity to phenylthiocarbamide (PTC) in Xibe and Mongol nationa-lities was carried out in Yili district of Xinjiang, by using the threshold-method and totally1800 persons (1121 Xibes and 679 Mongols) were investigated. The result showed that percen-tage of non-tasters was 19.98% for Xibe and 15.17% for Mongol; the taster-blindness gene fre-quency of Xibe and Mongolwas0.4470 and 0.3895, respectively; and the mean taste thresholdwas8.53-1.25 for Xibe and 8.10t1.49 for M ongol.
    The incidence of non-tasters jn one group(at age 17-- 50 years) was higher than that inanother group (at age 9--16 years). There was a significant difference in taste-blindness fre-quency between males and females in Mongol but not in Xibe.
    The comparison by ABO blood- -group gene frequencies and tongue. -rolling ability betweennon-tasters and tasters showed no relationship to response.

    The transferrin(Tf) polymorphism of Ew enki, Mongolian, Oroqen, Tahur, Tibetan, Man-chu, Korean, Hui, Han(Xian, Harbin), Uighur nationalities living in China was investigate?by means of ultra-thin polyacrylamide gel iso eletric focusing. The results showed that ·he·Tf*C1 gene frequencies of eleven groups were higher than 0.7: Ewenki 0.7571, Oroqen 0.7467,Uighur 0.7445, Mongolian 0.7433, Tahur 0.7417, Han(Xian) 0.7205, Manchu 0.7195, Korean0.7136, Tibetan 0.7096, Hui 0.7077, Han(Harbin) 0.7056, respectively. The Tf*C2 was the se-cond major allele in these ethnical groups. The order of . Tf*C2 allelefrequenciesroughlywas opposite to Tf*Cl. In addition, some rare phenotypes werefound, such as TfBDchi in Mongolian; TfDchiDchi in Han(Xian) and TfBCl in Manchu.

    The genetic polymorphism of the fourth complement component (C4) in Uigur, Miao, Yaoand Zhuang Nationalities in China was investigated using the methodsrecommended by thte4th International Workshop for the Genetics of Complement and the advanced techniques oflaser densitometry scanning, and compared with the data of Han Nationality prlviously deter-mined by us. As to C4, the frequency of C4A3 was found as the highest among five nationalities; the remaining frequencies orders were C4A2, Q0, 4, 1 successively among four nationalities except for Uigur. As to C4B, the frequency of C4B1 was found as the highest among fivepopulations; the remaining freq?encies orders were C4B2, Q0, 3 in Han and Uigur, 92, Q0,2, 3 in Miao and Zhuang, Q0, 2, 92 in Yao respectively. The differences among five populations were focused on allotypes of C4A2, C4B2, C4AQ0 and C4BQ0. The differences of C4genetic frequencies among Chinese Han, Japanese, Caucasian, and Negroid were also discussed.

    Spectrum absor ption method was used to determine the contents of microelements (suchas Zn, Cu,Ca,Mg and Fe) in the blood and in the hair of the Han, Uigur, Kazak people innormal health state. The results showed that ·he above mentiond elements in the hair arrangedsuccessively downwards as Ca> Zn> Mg>Fe>Cu and those in the blood of Han people arran-ged as Fe> Ca> Mg> Zn>Cu, of Uigur an·l Kazak people as Fe> Mg> Ca> Zn> Cu.
    Besides, thecontentof the microelement Mg in the blool and in 1he hair of the Uigurand Kazak people is obviously higher than that of the Han people's (p <0.05).

    Anthropometrical characters that related significantly with finger prints are hand bread .th, spinal breadth.
    Anthropometrical characters that related significantly witth palm prints arc nasal height,head breadth, minimum frontal breadth, inter- canthic diameter, extra- -canthic diameter, lengthof upper arm, length of thigh, length of leg, foor length, foot breadth, girth of head, girth ofchest, girth of wrist, girth of thigh, girth of calf.

    This paper reports the survey results of pa lmar patterns on 460 normal people of Man na-tionality. The palmar patterns studied in this paper are as follows: main line A. B. C. D;main line index(MLI); main line index of tra nsversality MLIT); fold-palm (a complex palmar flexion crease) and main line formula.
    The average values of MLl is 6.57±11.59(SD). It has no significant difference betweensexes(P > 0.05), but has significant difference between left and right hands. The average values of MLIT is 22.46±3.58(SD). It has significant difference between sexes and between left and right hands.
    The frequency of fold-palm is 3.05% (male: 1.09%, female: 5.00%). The bilateral symmetry of D.C.B.A main line formula is 36.52%. The major type of D.C.B.A main line formulais 7.5’’.5'3 (23.04%).

    The hand dermatoglyphics of 481 schizophrenic patients have been studied and compared with those of 180 normal persons. The results showed that the percentage of abnormal pal-mar creases was higher than the control. The main features 'were wrinkles-palm, whichwas .72.02±1.45% (control was 38 ±2.56%). The divergence of the ends of three main palmarcrease has higher percentage than the normal. Percentages of five patterns of the palmar crease were different between patients and the normal. The fingerprint of whorl was moreabundant, so the index of the whorl and loop was high, TFRC was high (161.87 +35.54). Theangleatd was larger (42.7°±415.54), a-b RC was low (39±15.32) on average.Five markers( wrinkes-palm, end divergence of three main palmar creases, angle atd, palmar creases of transverse patterns, and otherabnormalhand dermatoglyphics) have been adoptedto esti-mate. The full mark was 100. If the score of hand dermatoglyphics of a patient is more than70, he is a suffer from schizophrenia.

    The percentage of the fingerprint in ulnar loops is slightly lower and whorls slightly higher than the normal.
    Palmar crease in normal type is low but transitional types are high, atd angle countis a little larger.

    13 Francoi's leaf monkeys (5 males and 8 females) and 7 Phayre's leaf monkeys (2 malesand 5 females) were used to observe the dermatoglyphics on the hands and feet, The patter nsexamined include digital end I-IV, interdigital area, thenear and hypothenar, the triradius andflexure lines on the plams and soles. The results are as follows:
    1) All of the patterns on thedigital end are sinus primarius. There exist four kinds ofpatterns in the seven areas of the plams, that is L(looped form), o (opened field form). W(whorled form) and Z (composite form). However, most of them are the L forms. On the so-les, six kinds of them, L. 0. W., A (arches), A and U (unknown form) appear. Like onthe palm, most of them are the L pattern.
    2) Number of the triradius is different on the palms. 5-- -7 on the palm which constantlyexist tl and t7 for the P. francoisi, tl, t3 and t7 for the P. phayrei; 4--6 on the soles whichconstantly represent t2, t9, and tl3 for the P. francoisi, t9 and tl3 for P. phayrei 1.
    3) Flexure lines form joint lines of the skin on the palms and soles. There exist 1 to 2lines on the distal digits, 2 to 3 in interdigits. Flexure lines on the digital proximal form acontinuous common line which is attached by some lines with different shapes or by bran-ched one. There exist two flexure lines on the palms and soles. Two flexure lines on the wri-st, which sometimes is branched away, usually. are recorded. The longitudinal flexurelines ofthe radialis and tibialis sides are the constant on the plams and soles.
    4) Multivariate analysis (R cluster analysis) demonstrates the relationship between thepatterns for these two leaf monkeys.
