• Electrolyte homeostasis and the renin-angiotensin-aldosterone axis were studied to explain hypertensive states in pregnancy, contrasting normal, hypertensive, and preeclamptic physiology via aldosterone secretion, salt handling, and renin patterns [14], [15], [16], [11], [7].

• Etiology, incidence, and heredity of preeclampsia/toxaemia were framed as a pregnancy-related epidemiological problem, highlighting inheritance patterns, incidence data, and preventive concepts across early research [10], [6], [4], [9], [19].

• Clinical patterns and management of hypertension in pregnancy were explored by contrasting toxemic and non-toxemic forms and evaluating strategies to prevent eclampsia via obstetric management and risk profiling [1], [2], [3], [4], [6].

• Endocrine milieu and pregnancy outcomes were examined through steroid hormones, aldosterone dynamics, and related endocrine parameters in normal pregnancy and severe preeclampsia, linking endocrine changes to maternal-fetal health [8], [14], [15], [16].

• Renal involvement in pregnancy and preeclampsia was investigated via nephropathy, bacilluria, and electrolyte disturbances, framing kidney pathology as a central aspect of maternal health and obstetric risk [19], [13], [7].
