Summary of the main results

1. Parasitological Observations
Table 3 shows the ova counts before treatment and the number of helminths collected during the three days after treatment. Some men did not have ova in the initial stool examination, but expelled parasites after treatment. Fifteen men also had Trichuris trichiura and one of them had Taenia saginata.

After treatment all analyses were negative for Ascaris lumbricoides and hookworm, but 13 men still had T. trichiura (100 to 300 eggs/g of faeces).

2. Body Weight
Changes before and after deworming were small and inconsistent.

3. Nitrogen Digestibility and Balance
Group results are summarized in table 4. The men in group C (without ascaris) had lower faecal nitrogen and higher apparent nitrogen digestibility after treatment. Although group B showed higher urinary nitrogen excretion after treatment, nitrogen balance, biological value, and NPU did not change in any group.

4. Dietary Energy Absorption
Before treatment, the apparent absorption was (mean S.D.) 95.1 2.0, 94.6 2.8, and 94.3 2.8 per cent in groups A, B, and C, respectively. It did not change with treatment.

5. Other Observations
Only one man with hookworm was anaemic, as shown in table 5 (11.5 9 haemoglobin/100 ml). All men with hookworm showed slight increases in haemoglobin after treat ment. All other biochemical indicators remained constant, within normal ranges.
