An open clinical study of ofloxacin in respiratory tract infections was conducted with patients receiving daily doses of ofloxacin 300 mg, 400 mg or 600 mg. The duration of treatment was 6 to 14 days for 70% of the patients. Ofloxacin was effective in 668 of 828 patients analysed (80.7%). Of 293 patients with upper respiratory infections, the efficacy rate was 85.3%. In 535 cases with lower respiratory infections, ofloxacin was effective in 78.1%. It is noteworthy that a 70% efficacy rate was obtained in 80 cases with intractable chronic diffuse panbronchiolitis primarily associated with Pseudomonas aeruginosa. There was no difference in the efficacy rate among various daily doses or severity of infections. In lower respiratory infections the bacterial eradication rate was 80.9% for Gram-positive aerobes (including 80% for Staphylococcus aureus and 76.5% for Streptococcus pneumoniae) and 72.1% for Gram-negative aerobes (including 92.6% for Klebsiella pneumoniae, 32.3% for P. aeruginosa and 97.1% for Haemophilus influenzae). Although there were no serious cases, adverse reactions were noted in 46 of 843 patients (5.5%): 38 cases (4.5%) of gastrointestinal tract reactions (nausea, vomiting, heartburn, etc.), 4 cases (0.5%) of hypersensitivity (e.g. eruption) and 19 (2.3%) of central nervous system effects (e.g. dizziness). Abnormal changes in laboratory findings included elevations of AST (1.2%) and ALT (1.5%) and an increase in the eosinophil count (1.7%).

Breynia officinalis has the Chinese proprietary name, Chi R Yun, which means dizziness or vertigo for 7 d. In daily practice, it has been used to treat venereal diseases, contusion, heart failure, growth retardation and conjunctivitis in combination with other traditional Chinese medicines. Two hospital-based cases of Breynia officinalis poisoning have been reported to the Poison Control Center. Case 1 was a 43-y-old female who consumed a mixture of 1500 g lower stem and root of Ji Mu Ju in boiled water in a suicide attempt. Her AST reached 264 and ALT reached 2443. Case 2 was a 51-y-old female who consumed 20 pieces of lower stem and root of Ji Mu Ju stewed with meat and 100 ml of wine to treat chronic contact dermatitis. Her AST reached 3815 and ALT reached 6625. In both cases Breynia officinalis was identified as the cause of poisoning. Poisoning in humans involves the neurologic, gastrointestinal, hepatic, urinary and respiratory systems. Hepatotoxic effects have been reported for some Chinese herbal medicines, but not Breynia officinalis: Breynia officinalis poisoning causes hepatocellular liver injury rather than cholestatic liver injury.

Sodium azide poisonings occur very rarely. The mechanism of sodium azide toxic effect has not yet been fully explained. Despite the lack of an explicit procedure for the cases of sodium azide poisonings, in vitro tests and rare case reports suggest that treatment with antidotes for cyanide poisoning victims can be effective. This study describes two cases of suicidal sodium azide ingestion. Case 1. 30-year-old male ingested ca. 180 mg of sodium azide. On admission to hospital, within 4 hours from poisoning, the man complained of dizziness and anxiety. Physical examination revealed horizontal nystagmus, flapping tremor, HR 135/min. In laboratory tests, higher blood concentration of lactates (3 mmol/l) was detected, as well as lower potassium concentration (3.4 mmol/L) and increased transaminase activity (ALT 74 U/l, AST 90 U/l). Electrocardiographic tests showed a negative T wave in limb lead III. Other results were within normal. As the patient ingested a toxic dose of sodium azide, he was treated according to the therapy prescription for cyanide poisoning (amyl nitrite inhalation followed by intravenous administration of sodium nitrite and sodium thiosulphate). ECG record of the last day of hospitalization (7th day of treatment) showed negative T waves in lead III, V4-V6. He was discharged from hospital in good condition. Case 2.23-year-old male ingested 10 g of sodium azide 1.5 hours prior to admission to hospital. At the beginning, the patient's condition was good, but it changed to critical state within the first hours of hospitalization. He developed a deep coma, respiratory and circulatory insufficiency, metabolic acidosis, cardiac dysrrhythmias and anuria. Cardiac activity monitoring showed alternating tachycardia (140 beats per minute) and bradycardia (48 beats per minute), numerous additional supraventricular and ventricular extrasystoles and sinus dysrrhythmia. Cardiac arrest (asystolia) occurred twice, the second incident with fatal outcome. The patient received supportive therapy, he was also treated according to the therapy prescription for cyanide poisoning. Circulatory disturbances observed in both cases have been described in literature as symptoms of sodium azide poisoning. However, available literature data are scarce and lack systematization, most of them coming from several decades ago. The lack of patient's consent for detailed examination of circulatory system and liver made it impossible to gather further knowledge on the subject. The efficacy of treatment with antidotes for cyanide poisoning has not been unequivocally determined for this kind of intoxication.
