Fig. 4. The average slope of log₁₀ diameter as a function of time for Li⁺-treated crane fly spermatocytes is dramatically reduced compared to that of control cells and recovers substantially upon myo-inositol addition. The average slopes (±s.d.) are control 0.0647±0.0295 (n=12), Li⁺ 0.0137±0.0065 (n=12) and Li⁺ plus myo-inositol 0.0341±0.0140 (n=7). Error bars represent s.d. Values are significantly different for control versus Li⁺ or Li⁺ versus myo-inositol (P<0.0004, Student's t-test), whereas the difference between the control and myo-inositol was borderline significant (P=0.021, Student's t-test).
