Using anatomical, hydrostatic, and statistical methods, liver volumes were assessed in 69 human fetuses of both sexes aged 18–30 weeks. No sex differences were found. The median of liver volume achieved by hydrostatic measurements increased from 6.57 cm3at 18–21 weeks through 14.36 cm3at 22–25 weeks to 20.77 cm3at 26–30 weeks, according to the following regression:y= −26.95 + 1.74×age ±Z  ×(−3.15 + 0.27×age). The median of liver volume calculated indirectly according to the formula liver volume = 0.55×liver length×liver transverse diameter×liver sagittal diameter increased from 12.41 cm3at 18–21 weeks through 28.21 cm3at 22–25 weeks to 49.69 cm3at 26–30 weeks. There was a strong relationship (r=0.91,p<0.001) between the liver volumes achieved by hydrostatic (x) and indirect (y) methods, expressed byy= −0.05 + 2.16x  ± 7.26. The liver volume should be calculated as follows liver volume = 0.26×liver length×liver transverse diameter×liver sagittal diameter. The age-specific liver volumes are of great relevance in the evaluation of the normal hepatic growth and the early diagnosis of fetal micro- and macrosomias.

It has been reported that explants of human fetal intestine can be maintained in culture for up to 21 days in a viable condition and that these organ cultures support the growth of a variety of known viral agents responsible for enteric disease. Scanning electron microscopy (SEM) has been undertaken on several series of these explants to determine their appearance under routine culture conditions.Fresh specimens of jejunum obtained from normal human fetuses were washed, dissected into l-4mm pieces, and cultured in modified Leibowitz L-15 medium at 34° C as previously described. Serial specimens were fixed each day in 3% glutaraldehyde for 90 minutes at room temperature, rinsed, dehydrated, and dried by the CO2 critical point method in a Denton DCP-1 device. Specimens were attached to aluminum stubs with 3M transfer tape No. 465, and one sample on each stub was carefully rolled along the adhesive such that villi were broken off to expose their interiors.
