Three dermatoglyphic traits, viz; finger patterns, finger ridge counts, and palmer a-b ridge counts of 57 (M-29; F-28) and 64 (M-29; F-35). Schizophrenics with and without positive family history respectively, and 65 controls (M-30, F-35), were analysed to determine their level of fluctuating asymmetry.Uniformly higher fluctuating asymmetry was observed in the loop ridge counts of second digits of males and females of both the groups of schizophrenics. Significantly increased symmetry in the right and left loop ridge counts in the fifth digits of the family history positive female patients was noted. Barring the family history positive female schizophrenics, the rest of the patient groups manifested higher fluctuating asymmetry in their right and left whorl ridge counts of fourth digits. Family history positive patients of both sexes and female patients with negative family history displayed higher fluctuating asymmetry in the right and left palmer a-b ridge counts.
分析了 57 名（男 29 名，女 28 名）和 64 名（男 29 名，女 35 名）有和无阳性家族史的精神分裂症患者以及 65 名对照者（男 30 名，女 35 名）的 3 项肤纹学特征，即指纹、指嵴计数和掌侧 a-b 嵴计数，以确定其波动不对称程度。在两组精神分裂症患者的男性和女性第二指环嵴计数中，均观察到均匀较高的波动不对称性。家族史阳性的女性患者的右手和左手第五指环嵴计数的对称性显著增加。除了家族史阳性的女性精神分裂症患者外，其余患者组的第四指的右和左手涡纹嵴计数表现出较高的波动不对称性。有阳性家族史的男性和女性患者以及无阳性家族史的女性患者的右手和左手掌侧 a-b 嵴计数的波动不对称性更高。
